A transmission belt (B) which comprises a belt main body (10) constituted of rubber and including core wires (14) embedded therein. The core wires (14) are each constituted of a plied yarn which has a total fineness of 4,000-5,000 dtex and which is configured of four first twists each obtained by unidirectionally first-twisting, at a twist multiplier of 1,200-1,350, a para-aramid fiber bundle having a fineness of 1,000-1,250 dtex, the four first twists having been upper-twisted in the direction opposite to the first twisting at a twist multiplier of 900-1,100. |
