PROBLEM TO BE SOLVED: To provide a coating film removing method capable of easily and accurately removing an unnecessary coating film from a cylindrical substrate lower outer peripheral surface by an immersion coating method.SOLUTION: A coating film removing method for removing an unnecessary coating film from a cylindrical substrate lower outer peripheral surface by an immersion coating method includes the solvent supply step of supplying a solvent into a substrate through an opening for discharging the solvent, the outer peripheral surface coating film removing member abutting step of abutting an outer peripheral surface coating film removing member on the upper end to the lower end of the coating film of the removed part of the outer peripheral surface of the substrate by using the outer peripheral surface coating film removing member for removing the coating film of the removed part of the outer peripheral surface of the substrate as the coating film removing member, and the outer peripheral surface coating film removing step of relatively rotating, while abutting the outer peripheral surface coating film removing member on the upper end to the lower end of the coating film of the removed part of the outer peripheral surface of the substrate and while supplying the solvent supplied into the substrate to subsequently flow to the lower end of the substrate to the abutted part of the coating film of the removed part of the outer peripheral surface and the outer peripheral surface coating film removing member, the substrate and the outer peripheral surface coating film removing member to rub each other, and removing the coating film of the removed part of the outer peripheral surface.SELECTED DRAWING: Figure 1 【課題】浸漬塗布法による円筒状基体下方外周面の不要な塗膜を容易且つ正確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】浸漬塗布法による円筒状基体下方外周面の不要な塗膜を除去する塗膜除去方法であって、溶剤が吐出される開口から基体の内部に溶剤を供給する溶剤供給工程、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の塗膜の上端から下端まで外周面塗膜除去部材を当接する外周面塗膜除去部材当接工程、および基体の外周面の被除去部の塗膜の上端から下端まで外周面塗膜除去部材を当接させたまま、基体の内部に供給された後に基体の下端に流れた溶剤を、外周面の被除去部の塗膜と外周面塗膜除去部材の当接部に供給しながら、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、外周面の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。【選択図】図１
