Abstract
A cutting method of the invention cuts a flat wire covered with a film, using a pair of first blades, and a second blade that is arranged between the pair of first blades. This cutting method includes a step of forming tapered cuts in an upper surface of the flat wire, by the pair of first blades cutting part way into the flat wire in a thickness direction, from the upper surface of the flat wire, and a step of cutting the flat wire by the second blade, between the two cuts, so as to form a chamfer on both side surfaces next to the upper surface of the flat wire.
