In a woven belt and a seat belt apparatus using the same, it is an object to improve the abrasion resistance thereof. A woven belt 101 is made by weaving warp thread 102 extending in substantially the longitudinal direction of webbing and weft thread 103 extending in substantially the width direction of the webbing. Employed as at least either of the warp thread 102 and the weft thread 103 is fiber bundle containing thermal adhesion yarns (for example, each comprising a low melting point filament component 206 having a relatively low melting point and a high melting point filament component 207 having a relatively high melting point), thereby improving the strength of the fiber bundle and thus improving the entire abrasion resistance of the woven belt 101.
