Abstract
A foam molded product capable of preventing generation of an underfill portion due to a concave portion and a convex portion formed on a surface of the foam molded product and suppressing increase in cost, a method for producing the foam molded product, a molding die structure of the foam molded product, and a vehicle seat pad using the foam molded product are provided. A foam molded product 10 formed by integrally molding a foam body 12 made of a foamable resin material M and including a shape deformation section 26 that is a concave strip or a convex strip on a surface, and a sheet-shaped support member 14 covering a surface opposing a formation face of the shape deformation section 26 of the foam body 12. In the support member 14 of the foam molded product 10, a projected portion 16 is provided in a region opposing the shape deformation section 26 and/or a vicinity of the region, and the projected portion 16 is in a columnar shape extending in an extending direction of the shape deformation section 26.
