Zusammenfassung:	PURPOSE:To provide a resin foam molded piece production method in which a defective quality, such as a sinkage caused by a foaming gas or the like, can be easily prevented from occurring. CONSTITUTION:A skin material 3 is disposed on an inner wall surface of a lower mold 12 in a mold 1. A core 2 is disposed in the lower mold 12. Thereafter, a foamable resin material is injected and thermally foamed to be molded into a resin foam molded piece. In this production method, vent holes 41, 42 are respectively provided in undercut parts 31, 32 of the skin material 3 at least one in each. In addition, the vent holes 41, 42 provided in the undercut parts 31, 32 cannot be seen from outside when the resin foam molded piece is installed.
