PROBLEM TO BE SOLVED: To provide a seat core material which inhibits friction sound caused by slide movement of contact surfaces of a cushion layer and the seat core material.SOLUTION: A seat part 3 includes: a seat core material 4 formed by rigid synthetic resin foam; and a cushion layer 5 formed by soft synthetic resin foam covering the seat core material. In the seat core material, projections 10 extending in a standing direction 9 of the seat core material are provided in a standing part 7 of the seat core material which contacts with the cushion layer and faces a calf of a body.SELECTED DRAWING: Figure 1
