Summary:There is provided a hook-and-loop fastener manufacturing method. Injection molding is performed to form a molded product in which a pillar group and a base plate having a surface from which the pillar group protrudes are integrated into a unified body. A tip part of the pillar group is cut to form a cut product in which a small pillar group shorter than the pillar group and the base plate are integrated into a unified body. A tip part of the small pillar group is melted to form pillar body portions which are non-melted portions and engaging portions which are melted portions and thicker than the pillar body portions from small pillars. The engaging portions are cooled to determine shapes of a plurality of engaging elements including the pillar body portions and the engaging portions.
