Abstract
A shaped hook member of hook-and-loop fastener including a base plate and a plurality of hook-type engaging elements that rise from a surface of the base plate. The hook-type engaging elements are each tapered from the proximal end to the distal end, and are each curved from a point in the course from the proximal end to the distal end, and the distal end is directed toward the base plate. The plurality of hook-type engaging elements are arranged in rows extending in the same direction as the curving direction of the hook-type engaging elements, and the curving directions of the hook-type engaging elements in two adjacent rows or two adjacent units each of two or more rows are opposite to each other. The base plate and the hook-type engaging element are formed of a semi-aromatic polyamide resin containing a semi-aromatic polyamide and an elastomer.
