1. A multi-axis inertial force sensor comprising:
a mounting material having an installation surface;
a plurality of blocks arranged on the installation surface of the mounting material and respectively having inclined surfaces inclined with respect to the installation surface; and
a plurality of sensors respectively arranged on the inclined surfaces of the plurality of blocks to detect an inertial force corresponding to main axes,
wherein
the plurality of blocks has a positioning portion that relatively determines a position of a contact partner in contact with at least one or more of the plurality of blocks, and forms a pedestal by an assembly of the plurality of blocks where positions are determined relative to each other based on the positioning portion and where the inclined surfaces are oriented in different directions,
the plurality of sensors is respectively arranged on the inclined surfaces of the pedestal so that the main axes are oriented in different directions to detect vector components of the inertial force corresponding to the main axes,
the plurality of blocks includes a first block, a second block, a third block, and a fourth block, each of which is a triangular prism having one end surface and an other end surface shaped in a right triangle and connected to the inclined surface, and one side surface and an other side surface connected to the inclined surface and the end surfaces,
the inclined surface corresponds to an oblique side of the right triangle,
the one side surface of the first block, the one side surface of the second block, the one side surface of the third block, and the one side surface of the fourth block are arranged on the installation surface,
the other side surface of the first block and the other side surface of the second block face each other and are in contact with each other without a gap,
the first block, the second block and the third block are arranged without a gap by contacting each other such that the one end surface of the second block and the other end surface of the first block face the inclined surface of the third block, and
the first block, the second block and the fourth block are arranged without a gap by contacting each other such that the one end surface of the first block and the other end surface of the second block face the inclined surface of the fourth block.
