Abstract
The surface fastener includes a base portion, a fastener member that includes a plurality of engagement elements, and a masking member that is detachably held by the fastener member. The masking member covers an engaging area of the fastener member, at least a part of the engaging element is embedded in the masking member. A space portion is provided between the base portion and the masking member in the engaging area. Thus, a foam resin can be prevented from intruding the engaging area of the fastener member in foam-molding of the cushion body. The masking member is also easily peeled off from the fastener member after foam-molding.
