This invention provides a slider for use in sport goods, and its surface is smooth without any protrusion thereby providing no danger to a user. On a top surface of an upper wing of a slider body for slide fastener, a thread attachment portion for attaching a thread body as a pull and a fixing portion for fixing molded resin body formed by insert-molding synthetic resin on the upper wing are formed integrally with the slider body. The thread attachment portion is formed by arranging tongue pieces each having a narrowed tip in the center of the upper wing such that they oppose each other. The thread body is placed between the tongue pieces and the tongue pieces are crimped so as to fix the thread body. Further, tongue pieces slightly smaller than the aforementioned tongue pieces having the same shape are formed back and forth of the thread attachment portion and the tips thereof are crimped inward so as to form the fixing portion. Then, synthetic resin is insert-molded to bury and cover the thread attachment portion to which the thread body is already attached and the fixing portion so that a molded resin body is formed on the upper wing and fixed thereon. As a result, there is provided a slider whose body has a smooth surface and only contains a flexible thread body.
