To decrease a defect rate of products and to improve productivity by suppressing a trouble on gas permeability and generation of deformation and strain, and by make it possible to keep a good moldability for a long time continuous use.

This mold for press molding is constituted in such a way that a punching plate (2) is arranged on an opening part of a frame-like box body (1), and a resin mold (3) is integrally arranged on the outer surface of the punching plate (2) by inserting and curing a resin in an anchor-like state in a hole part (21) of the punching plate, and an air vent hole (5) passing through the anchor-like cured resin (31) in the hole part (21) of the punching plate is formed in the resin mold (3).
