Abstract
A toothed belt includes: a belt body having a flat band-shaped back rubber portion and tooth rubber portions placed on an inner circumferential side of the back rubber portion, the back rubber portion and the tooth rubber portions being each composed of a thermoplastic elastomer composition; a cord containing carbon filaments; and a tooth portion covering material provided on an inner circumferential side of the belt body and covering the tooth rubber portions. An elastomer component of the thermoplastic elastomer composition is a TPAE or a TPC, a hardness of the thermoplastic elastomer composition forming the back rubber portion is not less than 25 and not greater than 70, a hardness of the thermoplastic elastomer composition forming the tooth rubber portions is not less than 40 and not greater than 70, and the hardness of the thermoplastic elastomer composition forming the back rubber portion is not greater than the hardness of the thermoplastic elastomer composition forming the tooth rubber portions.
