To provide a mold capable of suppressing the occurrence of warpage caused by pressing force of split molds during molding and capable of developing excellent durability.

In the mold 1 having a product-molding part 5 for molding a sheetlike molded product on the parting part 4 of mutually opposed split molds and molding the molded product in a state that the split molds are clamped by pressing force, pressure receiving surfaces 12 are set to respective four peripheries of the product-molding part 5 in the parting part 4. Further, when a plurality of the product-molding parts 5 are provided the pressure receiving surfaces 12 are respectively set to four peripheries of the parting part 4 and the gaps between the product-molding parts 5.
