More Information
Summary:This fastener element (10) has a coupling head portion (11) and a tape holding portion (16) provided with a body portion (17), a first leg portion (18a), and a second leg portion (18b). The tape holding portion (16) has at least one notch portion (21) that is open on a tape holding surface (19), and a bulging portion (22) that bulges out adjacently with respect to a bottom surface (21a) in the element thickness direction of the notch portion (21). Such a fastener element (10) can be easily manufactured from a Y-shaped wire material (50). Furthermore, the slip strength and pull-out strength of the fastener element (10) can be increased by implanting the fastener element (10) in a fastener tape (3).
