PROBLEM TO BE SOLVED: To provide a novel display addition method suited to a stretchable area.SOLUTION: A stretchable area 20X is formed by superposing an elastic sheet layer between a first sheet layer and a second sheet layer. In a state where the elastic sheet layer is extended in the stretching direction along the surfaces of the first and second sheet layers, the first sheet layer and the second sheet layer are joined, via through-holes formed on the elastic sheet layer, at multiple dot-like joining parts 40 disposed at some intervals apart in the stretching direction and a direction orthogonal thereto. The first sheet layer and the second sheet layer are not joined with the elastic sheet layer other than at least the dot-like joining parts between the first sheet layer and the second sheet layer. Further in a natural length state of the elastic sheet layer, shrinkage creases extending in the direction orthogonal to the stretching direction are formed between the joining parts. The stretchable area 20X includes: a texture pattern area 70 formed of parts where the dot-like joining parts are regularly repeated; and a display area 80 in which non-joining parts 41 without dot-like joining parts are formed within the texture pattern area into a display shape.SELECTED DRAWING: Figure 8 |
