To secure a good ground continuity between a socket and a plug and an effective lock.

This shield connector has a socket 1 attached to a printed circuit board (Cl) and a plug 7 designed to be coupled by insertion into the socket. At least, one of the wall surfaces of the plug is covered with a shield 9a made of an electrical conductor material, and at least, one of the first wall surfaces of the socket 1 corresponding to the plug 7 is covered with shields 2, 4 each made of an electrical conductor material, with the shields 2, 4 extended toward the front end of the socket 1 by a plate piece made of at least one projection 22 which is pressed against the shield of the plug 7 during insertion of the plug 7 to form a spring so that current carrying contact between the shields of the plug 7 and the socket 1 is made possible.
