A connector which connects an IC card to a corresponding information input/output unit without cable and can be removed as needed has a structure in which a plurality of U-shaped conductive pieces formed of a sheet metal are fixed to a rectangular-rod-like insulating block. Each conductive piece has a central portion fixed to a corresponding notched portion formed in a side surface of the insulating block, a first contact portion extending from the central portion in one direction and bent at an almost right angle along the lower surface of the insulating block, and a second contact portion extending from the central portion in an opposite direction, held to be elastically deformed in a groove formed in the upper surface of the insulating block, and including an end portion projecting from the upper surface. As an embodiment, the following structure is disclosed. A pair of projection portions are formed on both the sides of the central portion of the conductive piece, the projection portions are bent so as to form a U shape having a bottom as the central portion, and the bent projection portions are fitted in the respective holes formed in the corresponding notched portion of the insulating block, so as to fix each conductive piece to the insulating block.
