MANUFACTURING METHOD OF TOOTHED BELT AND TOOTHED BELT

PROBLEM TO BE SOLVED: To provide a manufacturing method of a toothed belt that can easily manufacture a toothed belt in which a core wire is not exposed to a tooth bottom, and the core wire does not corrode easily.SOLUTION: The manufacturing method of a toothed belt 1A that includes: a belt body 11 in which a core wire 13 is buried; and two or more tooth parts 12, is characterized as follows. A cloth having water-absorptivity is laid at a mold that has core wire support projections to support the core wire 13 at the tips of two or more protrusions for forming the tooth parts 12 to at least cover the core wire support projections, then while maintaining the core wire 13 to be supported by the tips of the core wire support projections, a belt in which the cloth is integrally formed is formed, then an emulsion resin 17 is coated to the cloth of the part that covers the groove formed with the core wire support projections in the formed belt.
