12 of an IC 11 is pressed against the contact pin 10, some degree of wiping action is caused at a potion contacting a PCB terminal 13. As can be seen clearly from FIG. 1, the rotational radius of the contact portion of the terminal is short since a rotational axis of the contact pin 10 is very near to the PCB. Thus, it is difficult to perform wiping action in a wide area. Second, as the contact points of the integrated circuit lead 12 and the PCB terminal 13 are not aligned in a straight line and they are connected to each other via detouring path, there is a problem that the electrical length becomes longer. Third, when the pressure applied by the lead 12 of thechannel and on the outer side of the respective first channel, the channels being formed from the bottom surface of the contact pin housing and extending to cross all of the slots; a first elastic member and a second elastic member respectively installed within the first channel and the second channel, wherein the contact pins are inserted into the respective slots, and each of the contact pin engages with the first and second elastic members, and each of the contact pins includes a first contact portion protruding over the top surface of the contact pin housing for making contact with a lead of the integrated circuit and a second contact portion for making contact with one of the terminal of the PCB.
Also, the contact pin of the present
