The core wire (), the belt tooth portions (), and the belt groove portions () are integrated with one another by a rubber material (). It should be noted herein that the core thread () and the filament thread () are integrally twined around each other so that the filament thread () is formed in the shape of a plurality of loops around the core thread (). The filament thread () in the shape of the loops enters tooth root portions () of the belt tooth portions () to be arranged therein. As a result, the tooth root portions () are strengthened.
