It is an object of this invention to provide a resin molding die that is capable of suppressing, even when an undercut is provided on a core mold and an embossing process is performed on a cavity mold, generation of burrs attributed to the undercut and the embossing process. A resin molding die (1) of this invention includes: a core mold (4) including a protrusion (11) formed on a surface thereof as an undercut, the protrusion (11) being provided so as to form a through hole (105) in a resin-molded product (100); and a cavity mold (5) provided so as to be engageable with the core mold (4). The cavity mold (5) includes: a cavity main body (13) including an embossed surface that is opposed to the surface of the core mold (4), on which the protrusion (11) in provided, under a state in which the cavity mold (5) and the core mold (4) are engaged with each other; and an insert (15) provided to the cavity main body (13) so as to abut on the protrusion (11), the insert (15) including a mirror-fmished surface as an opposing surface (23) thereof that abuts on the protrusion (11). |
