ABSTRACT:
An IC socket comprises a socket body including a plurality of contacts for interconnecting an IC and a wiring board. Each of the contacts comprises a contacting arm including an upper end contact portion for a lead of an IC to overlie and contact, and a lower end contact portion including a downwardly facing projection capable of abutting with a wiring portion of the wiring board, and a pressing element projecting backwardly of the contacting arm from an area in the vicinity of a connecting portion between the projection and the contacting arm. The projection forming the lower end contact portion is received in an upwardly and downwardly open through-hole formed in the socket body, so as to be subjected to abutment with the wiring portion. A resilient body held by the socket body is interposed between the pressing element and the contacting arm to retain a standby posture of the contact, and the contact is turned forwardly about the projection received in the through-hole to thereby cause the pressing element to compress the resilient body, so that a contacting pressure between the upper end contact portion of the contacting arm and the IC lead is obtained by a restoring force of the resilient body.
