PURPOSE:To arrange contacts with high density by using the horizontal intermediate sections of the contacts having comparatively simple structure bent to a crank shape as cantilever springs for generating contact pressure. CONSTITUTION:A contact 3 consists of a spring material such as a square wire, a round wire, a plate material in narrow width or the like, and contact sections 31a abutted against the tips of signal pins 51 for an LSI 5 and stopper protrusions 31b positioning the contact sections 31a in the vertical direction so as to shape the same surfaces as the base of a recessed section 41 in a cover member 4 are formed to an upper edge face. Contactor holes 42 for accurately arranging the contact sections 51 are shaped where corresponding to the signal pins 51 having high density for the LSI in the cover member 4, but the contactor holes 42 can be disposed adjacently because the sectional shapes of vertical sections 31 in the contacts are simplified, and pitch intervals can be attained. When the LSI 5 is loaded and pressed, the vertical sections 31 in the contacts are displaced downward, and horizontal sections 32 are deflected, thus generating desired contact pressure.
