A socket contact includes a cylindrical sleeve, a plurality of cantilever-shaped spring pieces arranged in rotational symmetry with respect to the central line of the sleeve as a symmetric axis, and a base portion to which fixed ends of the plurality of spring pieces are fixed. The sleeve is movably mounted to the base portion, the plurality of spring pieces has bent portions between free ends and the fixed ends, the plurality of spring pieces is elastically deformed so that the free ends come close to each other when the sleeve is moved and covers the free ends, and a pin contact inserted among the plurality of spring pieces is sandwiched by the bent portions of the plurality of spring pieces elastically deformed by the moved sleeve, electrically connected, and held.
