摘要： To provide a method for manufacturing an outer panel in which takt time is shortened and of high designability. A method for manufacturing an outer panel performing a hemming process according to the present disclosure includes; performing a laser light irradiation process on an inner side of a steel sheet that serves as an outer panel to bend the steel sheet at a first angle, the laser light being irradiated along a ridgeline of a center part of a bend radius of the steel sheet, and performing the hemming process on the steel sheet at a timing that is after the laser irradiation process to bend the steel sheet at a second angle smaller than the first angle.
