A golf club head includes a face plate which is made of a first metal material, and a head body which is made of a second metal material with a melting point lower than that of the first metal material. The face plate has a front side formed with a hitting surface, a rear side opposite to the front side, a flange projecting from a periphery of the face plate adjacent to the rear side, and a shoulder formed on the periphery of the face plate along and anterior to the flange. The head body has a front portion which has a recess formed therein for receiving the face plate, a peripheral edge defining the recess, and an engagement portion formed integrally with the front portion in the peripheral edge and engaged intimately and precisely with the flange and the shoulder of the face plate during molding of the head body. The engagement portion has a groove extending along the peripheral edge and engaging the flange of the face plate so as to retain the face plate on the head body to form the golf club head.
