A disposable wearing article comprising an absorber having: a lengthwise direction; a widthwise direction which is orthogonal to the lengthwise direction; an inward direction which is oriented to a wearer; and an outer direction which is oriented to a side opposite to the inward direction, wherein: the absorber has, in a crotch portion region applied to a crotch portion of the wearer, a central portion which is formed at a central part of the absorber in the widthwise direction, a pair of side edge portions including a side edge of the absorber in the widthwise direction, and a pair of middle portions which are positioned between the central portion and the side edge portions; at the central portion, a central curve forming portion (44, 46) is formed along the lengthwise direction so that the absorber can be curved to be convex in the inward direction; at the middle portion, a pair of side curve forming portions are formed along the lengthwise direction so that the absorber can be curved to be convex in the outer direction; a top face of the absorber, which is formed to be convex in the inward direction by the central curve forming portion, is adapted to come into contact with the crotch portion; a thickness of the absorber at the central portion is smaller than a thickness of the absorber at the middle portion; the absorber has a first layer and a second layer which is superimposed on the first layer; the second layer is positioned at a skin contact surface side with the wearer; and the first layer is positioned at a non-contact surface side of the wearer; a central aperture is provided in the first layer; characterized in that: the side curve forming portion is formed of a side slit which is formed at the absorber along the lengthwise direction; a length of the side slits is smaller than that of the central aperture; a width of the side slits is smaller than that of the central aperture; the central curve forming portion is formed of a central elastic member which is disposed along the lengthwise direction, and is provided at a position which is superimposed with the central aperture in a thickness direction of the disposable wearing article. the absorber has, in a crotch portion region applied to a crotch portion of the wearer, a central portion which is formed at a central part of the absorber in the widthwise direction, a pair of side edge portions including a side edge of the absorber in the widthwise direction, and a pair of middle portions which are positioned between the central portion and the side edge portions; at the central portion, a central curve forming portion (44, 46) is formed along the lengthwise direction so that the absorber can be curved to be convex in the inward direction; at the middle portion, a pair of side curve forming portions are formed along the lengthwise direction so that the absorber can be curved to be convex in the outer direction; a top face of the absorber, which is formed to be convex in the inward direction by the central curve forming portion, is adapted to come into contact with the crotch portion; a thickness of the absorber at the central portion is smaller than a thickness of the absorber at the middle portion; the absorber has a first layer and a second layer which is superimposed on the first layer; the second layer is positioned at a skin contact surface side with the wearer; and the first layer is positioned at a non-contact surface side of the wearer; a central aperture is provided in the first layer; characterized in that: the side curve forming portion is formed of a side slit which is formed at the absorber along the lengthwise direction; a length of the side slits is smaller than that of the central aperture; a width of the side slits is smaller than that of the central aperture; the central curve forming portion is formed of a central elastic member which is disposed along the lengthwise direction, and is provided at a position which is superimposed with the central aperture in a thickness direction of the disposable wearing article. the side curve forming portion is formed of a side slit which is formed at the absorber along the lengthwise direction; a length of the side slits is smaller than that of the central aperture; a width of the side slits is smaller than that of the central aperture; the central curve forming portion is formed of a central elastic member which is disposed along the lengthwise direction, and is provided at a position which is superimposed with the central aperture in a thickness direction of the disposable wearing article.
