PROBLEM TO BE SOLVED: To provide a resin mold and a manufacturing method for the same that can prevent lack of resin burr of a thermoplastic resin member formed at the boundary between a sealing face and an exposure face in a thermosetting resin member in order to eliminate an additional step of removing the resin burr.SOLUTION: A resin mold has a thermosetting resin member 10 which is formed of a thermosetting resin material, a part of the surface thereof serving as a sealing face 11 while the residual portion of the surface serves as an exposure face 12, and a thermoplastic resin member 20 which is formed of thermoplastic resin material and seals the sealing face 11 so that the exposure face 12 of the thermosetting resin member 10 is exposed. At the boundary between the sealing face 11 and the exposure face 12, a part of the thermoplastic resin member 20 protrudes along the exposure face 12, and forms resin burr 21. A base portion of the resin burr on at least the exposure face 12 of the surface of the thermosetting resin member 10 is formed as a surface treated portion 13 which is subjected to a roughening treatment as a surface treatment of enhancing the adhesion to the thermoplastic resin member 20.SELECTED DRAWING: Figure 1 |
