Abstract
A slide fastener where each fastener element includes an upper half element portion disposed at a first surface side of a fastener tape and a lower half element portion disposed at a second surface side of the fastener tape. The upper half element portion includes a first tape-sandwiching portion and a first head portion of a tapered form that extends from the first tape-sandwiching portion. The upper half element portion has a tapered portion that gradually decreases in a dimension between front and rear side surfaces, in the tape length direction, of at least the first tape-sandwiching portion as it goes upward. Each fastener element can be lightweight, and the fastener element can look like a metal fastener element.
