Zusammenfassung:A core wires (12) of a toothed belt (B) are configured from twisted thread formed using a strip-shaped object in which filament bundles of high-strength glass fiber are integrated by means of a binderincluding a rubber component, at least one of a maleimide compound and a polyisocyanate compound, and a powdered inorganic filler. A surface of a reinforcing cloth (13) on the opposite side to a toothed belt main body (11) is coated with a surface-coating rubber layer (132) formed using a rubber composition containing a rubber component including hydrogenated nitrile rubber as a main constituent. 齿形带(B)的芯线(12)由拈线构成,该拈线由带状物形成,该带状物是高强度玻璃纤维的长丝束通过粘合剂一体化而得到的,该粘合剂中含有橡胶成分、马来酰亚胺系化合物和多异氰酸酯化合物中的至少一者、以及粉状无机填充剂。加强布(13)与齿形带带体(11)一侧相反一侧的表面由表面覆盖橡胶层(132)覆盖,表面覆盖橡胶层(132)由含有橡胶成分的橡胶组合物形成,该橡胶成分包括氢化丁腈橡胶作为主要成分。
