Abstract
A method for sewing a slide fastener includes forming end edge portion needle drop points in at least two positions, within an overlapped portion in which the work piece is folded, within a range more toward a tip side of an end edge portion of the work piece than half of an overlapped width, and within a range on an inner side of a width of a leg portion of an interlocking element. Sewing is performed with sewing thread passing from a head portion needle drop point to the end edge portion needle drop point of one end portion and sewing thread passing from the end edge portion needle drop point of another end portion to the head portion needle drop point of an adjacent interlocking element each passing either side of the leg portion.
