1. A socket configured to able of electrically connecting a first electric component and a second electric component together, the socket comprising:
a first contact pin configured to be capable of electrically connecting a ground terminal of the first electric component and a ground terminal of the second electric component;
a second contact pin configured to be capable of electrically connecting a terminal different from the ground terminal of the first electric component and a terminal different from the ground terminal of the second electric component; and
a base part that includes a first base part on a side of the first electric component and a second base part on a side of the second electric component, the base part being provided with a first through hole into which the first contact pin is inserted so as to be in contact with an inner wall of the first through hole and a second through hole into which the second contact pin is inserted so as not to be contact with an inner wall of the second through hole, the first through hole and the second through hole penetrating through the first base part and the second base part, wherein
the second base part is formed of an insulator,
a conductive film is formed on the inner wall of the first through hole in the second base part, and
the second through hole has a diameter larger than that of the first through hole and includes a through hole in which a conductive film formed of metal inert toward oxygen is formed on an inner surface and a through hole in which the conductive film is not formed and an inner surface exposed.
