Molded surface fastener and molded surface fastener manufacturing method

A molded surface fastener has engagement regions in which engaging elements are disposed in an erect manner and space regions with no engaging elements, the engagement regions and the space regions alternating in the longitudinal direction. Each space region has a pair of left and right vertical wall portions that are disposed on a substrate portion in an erect manner and a convex rib portion that protrudes from the center of the substrate portion in the width direction, and the convex rib portion is integrally connected to a main lateral wall portion disposed in the width direction of the engagement region. By implementing a simple cutting process, this molded surface fastener can be easily adapted to usages in which the fastener has to be in a curved shape bending in the width direction.
