Abstract

A composite seat core material is configured from: a base portion that is formed by fusing thermoplastic resin foamed particles having no through-hole to each other; and a connecting portion that is provided on the upper side of the base portion, and is formed by fusing foamed particles having through-holes to each other, the connecting portion having interconnected void spaces that communicates with the outside. With the outer surface of the connection portion partially exposed at the top surface of the composite seat core material, the base portion and the connecting portion are fixed and integrated with each other. A seat member is formed by laminating a polyurethane foam pad on the top surface of the composite seat core material.
