PROBLEM TO BE SOLVED: To make a temperature of a mold body 31 uniform and to improve a quality of a resin molding W. SOLUTION: Metal particles 53A to 53C for constituting a sintered metal layer 34 are continuously or stepwisely changed in a particle size along a flow of a heating medium so as to become small at a water input port 36 side of a heating medium and large at a drain port 37 side. Thus, a flow of the medium is, for example, fine at the port 36 side and thick at the drain port 37 side to make a temperature of the body 31 uniform.
