ABSTRACT:
An IC socket includes a base constructed integral with a top face for placing the resting portions of contact pins, an back face opposite to the top face, space passing through the base just under the back face, a plurality of first slit holes extending outwardly from the space, and a plurality of second slit holes arranged among the first slit holes adjacent to one another and outside the first slit holes. First contact pins are such that their pillar portions are inserted in the first slit holes, and second contact pins are such that their pillar portions are inserted in the second slit holes. In this way, all the contact pins is mounted to the base. The first and second contact pins are electrically connected with the leads of an integrated circuit by sandwiching the leads between the resting portions and the contact portions of the contact pins. Thus, in the IC socket, it is possible to reduce the product variation with respect to the contact resistance between each of the leads of the integrated circuit and each of the contact pins, and to mold the base with a relatively simple die.
