摘要： A seat pad (1) includes a surface portion (1a) configured of a polyurethane foam (11). In the surface portion (1a), wiring grooves (2) for wiring a wire harness (3) are formed. Each wiring groove (2) has a groove width W narrower than the diameter (φ 3) of the harness (3), and a groove depth (D) deeper than the diameter φ3 of the harness (3). A seat pad manufacturing method uses, as a molding die, a molding die that has groove-forming protrusions to form the wiring grooves (2) and has holes formed in side surfaces of the groove-forming protrusions. A polyurethane foam material is supplied to an interior of the molding die, and when a molded product is removed from the molding die, molded portions formed in the holes are forcibly pulled out of the holes of the groove-forming protrusions.
