<p>On each block side face of the blocks of a belt (C) for transmitting high load, a ratio (B/A) of a dimension B extending in a belt thickness direction from a buried cord center line of a corresponding tension band (10) to an upper end of an upper pulley-contact face (22) to a dimension A extending in the belt thickness direction from the buried cord center line to a lower end of the upper pulley-contact face (22) is larger than or equal to 4.0, and a dimension G extending in the belt thickness direction from the buried cord center line to a middle of the upper pulley-contact face (22) is smaller than or equal to 2.3 mm.</p>
