A rope substitution belt which has a higher strength than a rope having the same mass, has a substantially circular section, and is equipped with belt portions for sewing on both sides. The belt is a narrow width woven fabric (10) including warps (6) and wefts (7) of synthetic fiber filaments. The belt includes a main body portion (2), a belt portion (4) and a connecting portion (3) for connecting the main body portion (2) to the belt portion (4), that are disposed in a longitudinal direction. The main body portion (2) has a structure with wadding yarns (5) which are woven into a hollow woven structure. The warp density coefficient in the hollow woven structure portion (22) is set to be not greater than 0.700. The belt portion (4) has a structure with a part, or the whole, of the wadding yarns (5) which are so arranged as to cross the wefts with the warps (6) of the hollow woven structure of the main body portion (2). The belt portion (4) has a width W which is at least 2.0 times the width W of the main body portion (2). The connecting portion (3) is constituted such that while the width is gradually changed, it step-wise shifts over a plurality of stages to the woven structure of …
