PROBLEM TO BE SOLVED: To provide a coating film removing method that is capable of efficiently removing an unnecessary coating film from the lower outer peripheral surface of a cylindrical substrate.SOLUTION: The coating film removing method for removing a coating film from the lower outer peripheral surface of a cylindrical substrate has: the outer periphery coating film removing member abutting step of abutting so as to form a space by a groove shape and a substrate by using an outer periphery coating film removing member for removing a coating film from the removed part of the outer peripheral surface of the substrate as a coating film removing member, and opposing a surface having the groove shape of the outer periphery coating film removing member to the removed part of the outer peripheral surface of the substrate; the step of supplying a solvent to the space by causing the solvent to ooze up from the lower end of the space; and the outer periphery coating film removing step of removing the coating film from the removed part by relatively rotating the substrate and the outer periphery coating film removing member to rub each other.SELECTED DRAWING: Figure 1 【課題】円筒状基体下方外周面の不要な塗膜を精度よく効率的に除去することが可能な塗膜除去方法を提供する。【解決手段】円筒状基体下方外周面の塗膜を除去する塗膜除去方法であって、塗膜除去部材として基体の外周面の被除去部の塗膜を除去する外周面塗膜除去部材を用い、基体の外周面の被除去部に外周面塗膜除去部材の溝形状を有する面を対向させ、該溝形状と該基体とで空間を形成するように当接する外周面塗膜除去部材当接工程、溶剤が該空間の下端よりしみ上がることで、該空間に該溶剤を供給する工程、および基体と外周面塗膜除去部材とを相対的に回転させて摺擦し、被除去部の塗膜を除去する外周面塗膜除去工程を有する塗膜除去方法。【選択図】図１
