Zusammenfassung:A molding die according to the present disclosure includes a tubular portion and a base portion that closes an end portion of the tubular portion at one side. A cut level difference Rδc1 in a roughness curve of an inner wall surface of the tubular portion is smaller than a cut level difference Rδc2 in a roughness curve of an inner wall bottom portion of the base portion. The cut level difference represents a difference between a cut level at a load length ratio of 25% in a roughness curve and a cut level at a load length ratio of 75% in the roughness curve.
