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.

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 γ of 45 degrees or less.

Disclosed is a pant type absorbent article having a back elastic belt comprising a waist guard portion extending towards the crotch region from a closed base line towards an open edge, wherein the waist guard portion is formed by a first inner waist fold extending from a second inner waist fold, the second inner waist fold extending from the inner sheet, and a first elastic member bonded between the first inner waist fold and the second inner waist fold, wherein the waist guard portion is partially bonded to the remainder of the elastic belt from which the first and second inner waist folds extend to define a pocket.

An absorbent article includes: an absorbent main, an abdominal-side band member having a central portion fixed to one end part in a vertical direction of the absorbent main body while covering the one end part from a non-skin side of the absorbent main body, and a back-side band member different from the abdominal-side band member. The back-side band member has a central portion fixed to an other end part in the vertical direction of the absorbent main body, while covering the other end part from the non-skin side of the absorbent main body. The back-side band member has a length in the vertical direction longer than the abdominal-side band member. Each of the abdominal-side and back-side band members has an elastic member. The abdominal-side band member and the absorbent main body overlap at an overlap portion, the overlap portion including at least a part where the elastic member is disconnected.

A wearable article includes a front and back elastic belts, a crotch region, a waist opening, and leg openings. Each elastic belt is a laminate having an inner sheet, an outer sheet, and an elastic member. Elastic adhesive bonding continuously bonds the elastic member for at least about 10 mm in the direction of stretch adjacent the side edges of the belts. A discrete patterned adhesive bonding is applied to at least one of the inner and outer sheets to intermittently bond the inner and outer sheets. The discrete patterned adhesive bonding extends substantially along the transverse direction between the elastic adhesive bonding, and substantially along the longitudinal direction between the distal and proximal edges of the elastic belts. The same adhesive agent provides the elastic adhesive and discrete patterned adhesive bonding. Heat bonds form side seams, and the remainder of the laminate is free of heat bonds.
