To securely remove an insulation film of a rectangular wire including a corner while reducing running cost.SOLUTION: A film removal method of a rectangular wire 1a includes: a first film removal step S2 for removing an insulation film 2a on a first side constituting a cross section of the rectangular wire 1a forming a rectangular shape; and a second film removal step S4 for removing an insulation film 2b on a second side which constitutes a cross section of the rectangular wire 1a with the first side and intersects with the first side. The method further includes a curvature radius reduction step S1 for performing a prescribed mold forming process on the rectangular wire 1a and reducing a curvature radius of a corner 4 between both sides before the second film removal step S4 performed later among the first and second film removal steps S2 and S4.SELECTED DRAWING: Figure 1 【課題】ランニングコストの低減化を図りつつも、角部を含む平角線の絶縁被膜を確実に除去可能とする。【解決手段】平角線１ａの被膜除去方法は、矩形状をなす平角線１ａの断面を構成する第一の辺側の絶縁被膜２ａを除去する第一被膜除去工程Ｓ２と、第一の辺と共に平角線１ａの断面を構成し第一の辺と直交する第二の辺側の絶縁被膜２ｂを除去する第二被膜除去工程Ｓ４とを備えると共に、第一及び第二被膜除去工程Ｓ２，Ｓ４のうち後に実施される第二被膜除去工程Ｓ４よりも前に、平角線１ａに所定の型成形を施して、双方の辺の間の角部４の曲率半径を小さくする曲率半径縮小工程Ｓ１をさらに備える。【選択図】図１
