摘要：
A method for producing a seat core material 1 that has a foamed molded substrate 2 and a frame member 3 embedded in a periphery thereof, which includes, as step (a), heating thermoplastic resin expanded beads in a mold cavity, in which the frame member 3 has been disposed, to fusion-bond the expanded beads to each other and to obtain the foamed molded substrate with the frame member 3 being embedded in the periphery thereof; and, as step (b), simultaneously with step (a) or after step (a), forming a void cavity S, S' in the foamed molded substrate 2 at a position along and adjacent to the frame member 3. The void cavity S, S' has a size and shape that allows a relative displacement between the frame member 3 and the foamed molded substrate 2 when the foamed molded substrate shrinks after step (b).
