An insulating film removal method according to the present disclosure includes first, second, and third removal steps. In the first removal step, an insulating film coated on a junction surface and an opposed surface opposed to the junction surface is removed, the junction surface being a surface where a rectangular conductor is joined with another rectangular conductor. In the second removal step, a corner of the rectangular conductor is removed so that a burr is formed on the junction surface and a side surface, the side surface adjoining the junction surface and the opposed surface. In the third removal step, the insulating film coated on the side surface is removed so that a burr is formed on the junction surface side. |
