Abstract

An induction hardening apparatus comprises heating coils (26) that inductively heat different parts of the treatment target portion (A) in an axial direction of the work (12), the work (12) and a heating coil (26) being relatively moved along a circumferential direction (R) of a treatment target portion (A). The heating coil (26) has a zigzag shape in which a bent portion (34) that is opened to one side in the axial direction and a bent portion (35) opened to the other side in the axial direction are alternately continuously arranged in opposed directions along the circumferential direction (R).
