Abstract
To provide an electronic device socket able to shorten conductive paths between terminals of an electronic device and contacts of a circuit board. An electronic device socket () wherein a socket partelectrically connecting a plurality of terminals of an electronic device to corresponding contacts of a circuit board has a plurality of through holesarranged corresponding to the positions of the terminals. Each through holehas an elastic membercomprised of a coil spring, provided with an upper part having elasticity along a longitudinal direction of the through hole and a lower part able to form a conductive path substantially parallel to an extension direction of the through hole, a plungerhaving conductivity biased from the elastic member toward the top surface in a second state where the electronic device is attached and the terminals and contacts of the circuit board are electrically connected, and a conductive filmformed at an inner surface of the through hole so as to electrically connect with near a part of the elastic member where a upper part of the elastic member and the plunger contact each other, and a lower part of the elastic member when the elastic member is compressed.
