PROBLEM TO BE SOLVED: To provide a seat cushion core material for a vehicle, which warps less, excels in dimension accuracy and is formed from thermoplastic resin foam particle molding integrated with a reinforcement member.SOLUTION: A seat cushion core material 1 for a vehicle comprises: thermoplastic resin foam particle molding 2 of approximately rectangular as viewed from above, which has thick parts 4 at a front 2a and both sides 2b; and an annular reinforcement member 3 insert-molded in a peripheral edge part thereof. In this seat cushion core material, the foam particle molding 3 has an approximately L-shaped slit 7 formed along the reinforcement member and inside the reinforcement members 3 embedded in the front and outer sides of a passenger sitting part, and a slit 9 intersecting the reinforcement member is formed in the thick part 4 and in a position where the reinforcement member 3 is embedded.SELECTED DRAWING: Figure 2
