To make it possible to efficiently remove an insulation film with high yield when manufacturing a rectangular wire.SOLUTION: A method for manufacturing a rectangular wire 1 includes a film removing step for removing part of an insulation film 2 of the rectangular wire 1. The film removing step has a gap formation step S2 of applying heat treatment to a predetermined region of the insulation film 2 of the rectangular wire 1 to form a predetermined gap 6 between the insulation film 2 and a conductor 5 that becomes a main body of the rectangular wire 1, and a peeling step S3 of peeling a predetermined region of the insulation film 2 from the conductor 5 of the rectangular wire 1 after forming the predetermined gap 6.SELECTED DRAWING: Figure 10 【課題】平角線を製造するに際し、効率よくかつ歩留まり良く絶縁被膜を除去可能とする。【解決手段】平角線１の製造方法は、平角線１の絶縁被膜２の一部を除去する被膜除去工程を具備する。被膜除去工程は、平角線１の絶縁被膜２のうち所定の領域に加熱処理を施して、絶縁被膜２と平角線１の本体となる導体５との間に所定の隙間６を形成する隙間形成工程Ｓ２と、所定の隙間６を形成した後、絶縁被膜２の所定の領域を平角線１の導体５から剥離する剥離工程Ｓ３とを有する。【選択図】図１０
