There is provided a slider for a slide fastener. A slider body includes an upper blade disposed at a front side of the slider body, which is a pull-tab attachment side, a lower blade disposed at a back side of the slider body, which is opposite to the front side, and a connecting post connecting the upper blade and the lower blade to each other. A fibrous fabric sheet is integrally fixed to a back surface of the lower blade at the back side, with an adhesive layer being interposed between the fibrous fabric sheet and the back surface of the lower blade.
