A socket assembly for accommodating an IC chip or package (IC) provided with a socket body having a generally rectangular configuration. A plurality of flat plate-like contact pins are arranged forming rows in parallel with each other so as to form rows along four sides of the socket body, respectively. Each contact pin has a base portion and an arm which extends curved upward from the base portion. An upward contact portion for coming into contact with a terminal of an IC is formed on one end of the base portion of the contact pin, and a connecting portion for the connection to the printed circuit board is formed on the other end of the base portion. Four sliders are arranged along the four sides of the socket body, respectively. Each slider is supported by the base portions and arms of the row-foring contact pins and can move between an open position for accommodating the IC and a pressing position for pressing against the IC by an elastic force of the arms to bring the terminals of the IC into press-contact with the contact portions of the contact pins.
