ABSTRACT:
A female member of a snap fastener with tape comprising a female button made of synthetic resin which is integrally molded on front and back faces of the tape so as to hold a peripheral edge of an attachment hole of the tape having at least one attachment hole and which has an engaging opening to be engaged with a male button at a substantially center portion of the female button. The female button has at least one mold hole extending in a front and back direction of the tape, and at least one portion of the tape extends to an inside of the female button across the mold hole. At least one cut-out recessed in a diameter direction of the female button is defined in a portion of an inner peripheral engaging face of the engaging opening, and a gate burr is formed at a bottom face of the cut-out. Therefore, in the snap button with tape, and a manufacturing method and a mold of the snap button, in spite of a mold with a simple structure having a small number of pairs of pin members, gate burrs are not exposed on a surface, and the snap button can be easily manufactured without a special step for removing the gates, and the button can be firmly secured to the tape.
