A high frequency relay comprises a contact base block having pairs of fixed contacts, contact members with movable contacts, and an electromagnet for moving the contact members to open and close the fixed contacts by the movable contacts. The contact base block comprises an injection-molded base having projections on its front surface, first metal films formed as the fixed contacts on top surfaces of the projections, second metal films formed as connection terminals for outside devices on a rear surface of the base, each of which corresponds to one of the first metal films, through holes each having a conductive material on its inner surface to make an electrical connection between one of the first metal films and the corresponding second metal film in the shortest distance, and a third metal film formed on the base to provide electrical isolation from the first and second metal films, which works as electromagnetic shield means as well as ground means.
