Abstract
There is provided a slide fastener and a method for manufacturing a slide fastener. A slide fastener is provided with: a pair of fastener tapes; a pair of fastener element rows provided respectively on the opposing tape-side edges of the pair of fastener tapes and having a plurality of fastener elements; and a slider configured to engage and disengage the pair of fastener element rows with and from each other. Each of the fastener element rows is composed of a monofilament which is made of synthetic resin. The monofilament has, on the surface thereof, a surface layer which can be colored with dyes. A roughened surface having a number of concaves is formed on the surfaces of the surface layer.
