Abstract
The present invention is one that intends to reduce the number of working processes necessary to provide a secondary conductor on the inner circumferential surface of a roll main body, and an induction heated roll apparatus including: a roll main body that is rotatably supported; and an induction heating mechanism that is provided inside the roll main body and has an induction coil for allowing the roll main body to inductively generate heat. In addition, on the inner circumferential surface of the roll main body, the secondary conductor is formed by build-up welding.
