Abstract
In a molded surface fastener, at least part of a substrate sheet and hook elements are molded of synthetic resin, and simultaneously with the molding of the substrate sheet, at least part of foundation structure of a pile woven or knit core sheet is integrated with the substrate sheet which is molded of synthetic resin in such a manner that loop elements in the form of piles standing from the pile woven or knit core sheet are exposed to the front surface of the substrate sheet. The height of the hook elements is greater than that of the loop elements, and the foundation structure of the pile woven or knit core sheet is a coarse woven or knit structure having adequate pores throughout its entire area to allow molten resin to pass through. The hook elements and loop elements stand on the same surface or either of the front and back surfaces of the substrate sheet.
