PROBLEM TO BE SOLVED: To provide an IC socket keeping stable properties against repeated burn-in, having an electric contact with a durable plated layer. SOLUTION: The IC socket, for testing an IC having many electrodes, is mounted on a test device through a socket board. the IC socket has many electric contacts 20 which electrically connect the electrodes of the IC to a test device through an electric circuit formed to a socket board, and the electric contacts 20 have nickel palladium plating layer at a contact point 20a contacting the electrode of the IC.
