The molded hook and loop fastener has multiple hook and loop fastener parts on which multiple engaging elements are disposed, and a connection member for connecting the hook and loop fastener parts. The hook and loop fastener parts have fixing parts which fix the connection member to backings. The backings have forward and rearward extensions that extend in the longitudinal direction from the positions where the fixing parts are disposed. The dimension in the longitudinal direction of the connection member at a connection part is set to be longer than the minimum interval between adjacent hook and loop fastener parts, thereby allowing the molded hook and loop fastener to be bent easily in the width direction, and allowing the forward and rearward extensions to prevent foam resin material from directly hitting lateral walls.
