Abstract
The method of the invention includes: placing a base member and a frame member having a thermal expansion coefficient different from a thermal expansion coefficient of the base member in a state in which the base member is stacked with the frame member and a thermosetting adhesive agent is interposed between the base member and the frame member; adhering the base member and the frame member by heating the base member, the frame member, and the adhesive agent from the state to a temperature equal to or higher than a curing temperature of the adhesive agent; and cooling the base member and the frame member from the curing temperature. The frame member in the state is warped so that a flatness error of the frame member after having been cooled becomes smaller than that in a case where the frame member is flat in the state.
