Abstract: A stretchable member has a second sheet layer with an exposed portion, first sheet layer, and elastic sheet interposed therebetween. The second and the first sheet layers are joined at multiple sheet joining portions arranged at intervals through joining holes penetrating the elastic sheet or via the elastic sheet, and vent holes each opened at least in a spread state by displacement of the edge of each joining hole away from the circumferential edge of each sheet joining portion in the stretchable direction ED. The colors of the external surface of the elastic sheet and of portions of the external surface of the first sheet layer observed through the vent holes are observable through the second sheet layer, and the color difference ?E between the colors of the external surface of the elastic sheet and of the external surface of the first sheet layer is 30 or more.

Abstract: A disposable wearable article has an elastic sheet stretchable structure in which a first and second sheet layer are bonded through joint holes penetrating an elastic sheet at a plurality of bonded portions arranged at intervals, wherein a part of the elastic sheet located in a stretchable region is printed with a first design, a part of the elastic sheet in the non-stretchable region is printed with a second design, the first design and the second design are the same when the stretchable and non-stretchable region are at an elongation at elastic limit, and a stretchable direction dimension of design elements of the first design when a stretch rate of the stretchable region is 130% or more is 80% or more of a stretchable direction dimension of design elements of the first design when the stretchable region is at the elongation at elastic limit.

Abstract: A disposable wearable article includes an elastic film stretchable structure in which an elastic film is laminated between a first sheet layer and a second sheet layer. The first sheet layer and the second sheet layer are bonded to each other through holes passing through the elastic film with many bonded portions arranged at intervals. A region having the elastic film stretchable structure includes a stretchable region that elastically stretches and contracts together with the elastic film. The stretchable region includes a plurality of elastic films disposed so as to have an overlapping portion. The number of laminated layers of the elastic film in a region located in an intermediate portion of the stretchable region in an orthogonal direction (XD) orthogonal to a stretchable direction (ED) is different from that in each of second regions adjacent to both sides of the first region.

Abstract: An elastic sheet stretchable structure in which a first sheet layer and a second sheet layer are bonded through joint holes penetrating an elastic film at a plurality of sheet joined portions arranged at intervals is included. Joined portion groups in the stretchable region are in a relationship of intersecting a stretchable direction line at respective positions in an orthogonal direction or in a relationship of not intersecting the stretchable direction line at a separation width of 0.5 mm or less in the orthogonal direction of the stretchable direction line. The joined portion groups are in a relationship of not intersecting an oblique line at a predetermined separation width in the orthogonal direction in an oblique line group of oblique lines q in the orthogonal direction intersecting the stretchable direction line within an angle range ? of 45 degrees or less.
