The present invention aims at improving the shock resistance of a block while reducing the noise of a belt running. A high-load drive V-belt B includes: at least one tension band 10 extending in an endless loop; and a plurality of blocks 20 engaged and secured to the tension band 10 at a predetermined pitch in a belt length direction of the tension band 10, wherein each of the plurality of blocks 20 includes a contact surface 30 to be in contact with a pulley on each of opposite end portions of the block 20 in a belt width direction, each of the plurality of blocks 20 includes a slope 31 formed so as to be continuous with a belt inner side of the contact surface 30 and inclined toward a center in the belt width direction with respect to the contact surface 30, and an angle of the slope 31 with respect to the contact surface 30 is 120 degrees or more and 140 degrees or less.
