A high frequency relay capable of effectively shielding a signal path, yet reducing a number of the parts forming the shield and the associated structure. The relay has a dielectric base mounting three fixed contacts arranged in a line and defined at upper ends of three contact terminals extending through the base. Two movable contact springs are utilized, each bridging the two adjacent fixed contacts for closing and opening a high frequency signal path between the two adjacent fixed contacts. Upstanding from the base is a pair of electromagnetic shield plates which define a shielded space therebetween for accommodating the three fixed contacts and the two movable contact springs. Each of the shield plates is configured to come into electrical contact with corresponding one of the movable contact springs moved in the contact opening position. Each shield plate is integrally formed with at least one ground terminal which extends continuously from a bottom of the shield plate through the base, and each shield plate is configured to cover the first and second movable contact springs over the full length thereof for completely shielding the high frequency signal path.
