Abstract
A manufacturing method for a cup-shaped member including a corrugated portion includes a drawing step, a preliminary processing step, and a finishing step. In the preliminary processing step, at least preliminary large diameter portions in a preliminary corrugated portion are each formed to have a width larger than the size of each of the large diameter portions of the corrugated portion, thereby reducing an ironing resistance in the manufacturing of the cup-shaped member.
