A method for producing a coating film is provided which has high adhesion between the skin and the coating film formed by an electrostatic spray. This method for producing a coating film involves a solution application step for applying a solution containing one or more of water, polyols and oils that are in a liquid state at 20 DEG C, and a electrostatic spray step for forming a coating film by electrostatically spraying a composition directly onto the skin； these two steps can be performed in that order or in reverse order. The aforementioned composition contains a component (a) and a component (b), below. (a) One or more volatile substances selected from the group consisting of water, alcohol and ketones. (b) A polymer that can form a coating film.本發明所提供的覆膜之製造方法，係提高皮膚、與利用靜電噴霧所形成覆膜間之密接性。本發明的覆膜之製造方法，係依序(或依顛倒順序)包括有：將含有從水、多元醇、及20℃下呈液態之油之中選擇1種或2種以上的液劑，施加於皮膚之液劑適用步驟；以及將組成物直接朝皮膚施行靜電噴霧而形成覆膜的靜電噴霧步驟。上述組成物係包括有以下的成分(a)及成分(b)：(a)從水、醇及酮所構成群組中選擇1種或2種以上的揮發性物質。(b)具覆膜形成能力的聚合物。
