Abstract: The present invention is to enable accurate formation of an elongate member while suppressing the occurrence of a shape defect. An electromagnetic forming device is provided with an electromagnetic coil, and a forming mold which is disposed along the electromagnetic coil and provides an elongate material to be formed with a formed shape. An electromagnetic force generated by means of the electromagnetic coil is caused to act on the material to be formed and the material to be formed is pressed onto the forming mold. In the electromagnetic forming device, the forming mold has a cross sectional shape that varies from one end to another in a longitudinal direction of the material to be formed. The forming mold is formed such that, as the material to be formed is moved parallel to the longitudinal direction, the shape of the material to be formed is gradually changed to a desired shape.
