Coil forming device and coil forming method

The problem to be solved by the present invention is to provide a coil forming device and a coil forming method that can wind a strip coil on a coil winding jig by shaping the strip coil so as to generate sufficient springback when the strip coil is wound on the coil winding jig. In order to solve the problem, the invention provides a coil forming device which is configured in such a manner that a strip coil is wound and conveyed at a winding start position at which the strip coil starts to be wound and conveyed, and that the whole side end part of the strip coil is completely accommodated in a sliding contact surface of a shaping member. And a sliding contact surface (23) that is sandwiched between the shaping member and the guide member (first guide member 19), and that has an end portion of the sliding contact surface in the direction of conveyance of the band-shaped coil as a point of force to the side end portion, said point of force being present within the side end portion until each side end portion o
