Abstract
Abstract A socket for receiving an electric part has a presser cover openably and closably connected to a socket body through a pivotal hinge. Metal frames are embedded in a synthetic resin frame defining an opening in the presser cover at the position of the electric part. The metal frames can be used as bearing portions of the pivotal hinge. Holes in the presser frame through which the metal frames are exposed permit the metal frames to act as a static electricity discharging device.
