A seat core material of the invention includes: a foamed particle molding; and a frame member buried in a peripheral edge of the foamed particle molding, the frame member is an annular frame including a front frame part, a rear frame part, and two side frame parts that connect the front frame part and the rear frame part to each other, the foamed particle molding includes a first slit continuously formed over a width direction of the foamed particle molding between the side frame parts, the first slit penetrating the foamed particle molding from an upper surface to a lower surface, and the foamed particle molding includes a connection in a part of the foamed particle molding outside both ends of the first slit in a width direction, a first slit being not formed in the connection, and a ratio (I/L) of a length (I) of the connection in a width direction to a length (L) of the foamed particle molding in the width direction at a portion where the connection is positioned is 0.02 to 0.2 on one side. A seat core material having reduced deformation, extremely excellent dimensional accuracy, sense of unity, and strength is thus provided. The frame member and the foamed particle molding are integrated in the seat core material.
