Abstract
A seat pad having a pad body made of a polyurethane foam molding, a ventilation passage extending along a pad back surface of the pad body, a duct member which is harder than the pad body forming an inner peripheral wall of the ventilation passage, and a back surface member provided along the pad back surface. The duct member and the back surface member are integrally foam-molded with the pad body. The back surface member has an overlapping portion which is not provided on a bottom surface of the ventilation passage but is provided so as to overlap the duct member in the direction perpendicular to the plane in a non-bottom area outside the bottom surface.
