Abstract
A fastener element has a central land portion and first and second bulging portions bulging from the central land portion toward the tape front surface side and the tape rear surface side in the element thickness direction. The first and second bulging portions respectively have a bulging end surface facing to the element thickness direction. The bulging end surface has a quadrilateral base end surface which is long in the element length direction and a tapered protrusion end surface protruding from the base end surface in the element width direction. Thus, it is possible to make the fastener element look like a single-sided metal element and to make a slide fastener which is formed by using the fastener elements lighter than a conventional slide fastener having single-sided metal elements.
