PROBLEM TO BE SOLVED: To further improve the feel in a superposed composite part for imparting a cushioning property by elastic deformation of a large number of projections.SOLUTION: Since a height dimension of a rib 20, that is, a cushion stroke gradually changes to a second dimension H2 from a first dimension H1 toward an upper end part from a lower end part, the feel is partially made different, and even when a request for the feel is partially different, the proper feel can be imparted with every part, and quality of a commodity is improved. Since the height dimension of the rib 20 also gradually changes, the occurrence of discomfort is prevented when the feel suddenly changes, and the quality of the commodity is improved even in this point. |
