The molded surface fastener has a plurality of engaging regions having engaging elements and a plurality of space regions disposed between the engaging regions. Each space region has a plurality of wall pieces standing on a substrate portion and intrusion-accepted space portions which allows a foam resin material to intrude across the wall pieces in foam molding of a cushion body. By that, deformation or breakage of the engaging element in a manufacturing process can be prevented. Moreover, the molded surface fastener is firmly fixed in a state that the engaging elements are exposed.
