Abstract
An electromagnetic welding method includes the steps of piling a metal plate and an electric wire on a coil which generates a magnetic field when a current is applied into the coil, with a core wire portion of a central part of the electric wire being exposed while core wire portions except the exposed core wire portion are coated with a coating member. The coil and the exposed core wire portion are arranged lined up along a diameter direction of the electric wire, and a current is applied into the coil to generate a magnetic field so as to generate an eddy current in both the metal plate and the exposed core wire portion, thereby welding the metal plate to the exposed core wire portion.
