Abstract
A toothed belt including a reinforcing layer with 0.05 mm to 0.2 mm thickness buried along a contour of tooth portions such that a maximum height from a bottom portion of the tooth portion to the reinforcing layer is in a range of 30% to 100% of a height from the bottom portion to a tooth tip, in which the reinforcing layer includes reinforcing fiber filaments arranged in a belt circumferential direction, in the reinforcing layer, a weight per unit area of fibers intersecting the belt circumferential direction is 30% or less of a weight per unit area of the reinforcing fiber filaments, the reinforcing layer has a structure where the reinforcing fiber filaments are arranged in the belt circumferential direction and bonded to form a sheet shape in an untwisted state, and a tensile modulus of the reinforcing fiber filament satisfies a specific condition.
