By specifying a structure and composition yarns of the base fabric of the same surface fastener, the ratio (A/B) of an area A of a range in which sound spectrum of a peeling-off sound Fourier-transformed in a range of 100 Hz to 15000 Hz is 100 Hz to 3000 Hz to an area B of a range in which sound spectrum of a peeling-off sound Fourier-transformed in a range of 100 Hz to 15000 Hz is 3000 Hz to 15000 Hz is 0.4 or more. Consequently, tone of a sound generated when the surface fastener is peeled off and when the surface fastener attached on a product is peeled off is shifted to a low tone side so as to reduce an uncomfortable sound to a lower tone thereby reducing a feeling of discomfort.
