Abstract
A cutting method and a cutting device of cutting a magnet body including a coating film feed, in a state where the magnet body in which cutout grooves serving as brittle sections are provided on a lower surface along cutting planned positions is supported by dies serving as two support points from the lower side, the magnet body to a position where the brittle section is arranged between both the support points, and press the magnet body from the upper side of a position offset rearward in the feeding direction from the brittle section between both the support points, so as to cut the magnet body into a cut magnet body and a magnet piece smaller than the cut magnet body while cutting the coating film.
