Abstract
A method for manufacturing a golf club head comprising the steps of abutting a joining end surface of a hosel to a joining end surface of a ball-striking member, rotating the hosel while the ball-striking member and the hosel are under pressing contact, thus heating the joining end surfaces of the two members by the heat of friction generated between the joining end surfaces, stopping the rotation of the hosel, and then applying a further, stronger pressure to the joining end surfaces, thus joining them together so as to form the ball-striking member and the hosel into an integral, single unit.
