1. A board that is configured to be mounted in a printing apparatus, the printing apparatus including a printing head and an accommodation section in which a liquid accommodation container can be mounted, the accommodation section including (i) a liquid introduction portion that introduces a liquid to the printing head, and (ii) a plurality of apparatus-side terminals, the board comprising:
a base member;
a device provided at the base member; and
a plurality of terminals that are each provided at the base member, wherein each of the plurality of terminals is electrically coupled to the device and includes a contact portion, and wherein the plurality of terminals includes:
a data terminal with a data contact portion that is arranged to contact a corresponding apparatus-side data terminal among the plurality of apparatus-side terminals when the board is mounted in the printing apparatus,
a clock terminal with a clock contact portion that is arranged to contact a corresponding apparatus-side clock terminal among the plurality of apparatus-side terminals when the board is mounted in the printing apparatus,
a reset terminal with a reset contact portion that is arranged to contact a corresponding apparatus-side reset terminal among the plurality of apparatus-side terminals when the board is mounted in the printing apparatus,
a power-source terminal with a power-source contact portion that is arranged to contact a corresponding apparatus-side power-source terminal among the plurality of apparatus-side terminals when the board is mounted in the printing apparatus, and
a ground terminal with a ground contact portion that is arranged to contact a corresponding apparatus-side ground terminal among the plurality of apparatus-side terminals when the board is mounted in the printing apparatus,
and wherein the board is arranged so that, in a plan view, when (i) two orthogonal straight lines are set as a first virtual line and a second virtual line, and (ii) a position of each contact portion on the base member is projected in a direction perpendicular to the second virtual line onto the second virtual line as a projection position, including projection positions of the data contact portion, the clock contact portion, the reset contact portion, the power-source contact portion, and the ground contact portion,
(a) the projection positions of all contact portions on the base member are different from each other, and the first virtual line passes through a middle between two projection positions that are farthest from each other among the projection positions of all of the contact portions,
(b) the first virtual line defines a first region of the base member on one side of the first virtual line and a second region of the base member on the other side of the first virtual line, and some contact portions are arranged in the first region including at least the data contact portion, the clock contact portion, the reset contact portion, and the power-source contact portion, and remaining contact portions are arranged in the second region including at least the ground contact portion, and
(c) the some contact portions are arranged in a first pattern in the first region and the remaining contact portions are arranged in a second pattern in the second region, and the first pattern and the second pattern are asymmetrical to each other with respect to the first virtual line.
