The bonding composition according to the present invention contains: first metal particles the surfaces of which are covered with an amine having a polar group and which have an average particle size of 20-100 nm; second metal particles having an average particle size of 200-500 nm; a dispersion medium; and a polymer-dispersing agent. The weight ratio of the first metal particles to the second metal particles is 20:80 to 80:20. The concentration of the solid content thereof is at least 90 wt%. The dispersion medium contains a diol, and has a viscosity of 100-300 mPa·s at 25°C.

A transmission belt (B) is provided with an elastomer belt main body (11), and core wires (12) that are made of carbon fibers, embedded in the belt main body (11), and provided so as to form a spiral having a pitch in the belt width direction. When the core wires (12) are viewed from the side direction orthogonal to the length direction of the core wires, the angle θ formed by an outermost filament (F) (in a carbon fiber filament bundle forming the core wires (12)) with respect to the length direction of the core wires (12) is between 8° and 20°.
0.20.2 per millimeter of belt width when the belt elongation rate is 0.2% is at least 70 N/mm, the quantity of backlash from a toothed pulley is 0.10 mm–0.75 mm, the hardness of the belt body is at least 89° as measured with JIS K 6253 durometer type A, and the coefficient of dynamic friction on the surface is 1.5 or less.
