Abstract
An end portion of a coil wire is wound around a coil terminal to form a wound portion. Then, air is supplied to the wound portion. While the air is supplied to the wound portion, heat is supplied in a first stage to the coil terminal, and thus a heat resistant coating of the coil wire is burnt and is removed from the coil wire located in the wound portion. Thereafter, heat is supplied in a second stage to the coil terminal, and thus a protrusion of the coil terminal is melted to join the coil wire and the coil terminal to each other at the wound portion.
