A socket for an electric component includes: a socket main body having a receiving portion which receives an electric component such as an IC package; a socket cover supported to be capable of turning by a first turning shaft provided in a vicinity of one side end of the socket main body to turn to thereby open or close the housing portion; and a radiating member mounted to the socket cover and is in contact with the electric component received in the receiving portion to radiate heat from the electric component in a state of the socket cover being closed. The socket cover has an opening portion formed in a position corresponding to the receiving portion of the socket main body in the closed state, and the radiating member is supported to be capable of turning by a second turning shaft parallel to the first turning shaft in the opening of the socket cover.
