TEST SOCKET

A test socket is provided and includes a base with a first surface, a second surface opposing the first surface and through holes, a conductive elastic sheet located on the first surface, and a plurality of elastic metal members with first contact ends facing toward the conductive elastic sheet. The first contact ends include bumps suitable for inserting into the conductive elastic sheet, and each elastic metal member may be prevented from being contaminated by covering the base with the conductive elastic sheet. When the elastic metal members are pressured to insert the bumps into the conductive elastic sheet, a low resistance better than the resistance of the elastic metal members without squeezing can be obtained. When the bumps are inserted into the conductive elastic sheet, the surface of the bumps can be cleaned and the elastic metal members are stably in contact with the conductive elastic sheet.
