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, the absorber including a water absorbent polymer, 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 (S L, S R) including a side edge of the absorber in the widthwise direction, and a pair of middle portions (M L, M R) which are positioned between the central portion and the side edge portions; at the central portion, a central curve forming portion is formed along the lengthwise direction so that the absorber can be curved to be convex in the inward direction; at each of the middle portions, a side curve forming portion is formed along the lengthwise direction so that the absorber can be curved to be convex in the outward direction; an average total weight of the water absorbent polymer at the central portion and the pair of side edge portions (S L, S R) is smaller than an average total weight of the water absorbent polymer at the middle portions (M L, M R); and a thickness of the absorber in the central portion and the side edge portions is smaller than a thickness of the absorber at the middle portion. 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, the absorber including a water absorbent polymer, 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 (S L, S R) including a side edge of the absorber in the widthwise direction, and a pair of middle portions (M L, M R) which are positioned between the central portion and the side edge portions; at the central portion, a central curve forming portion is formed along the lengthwise direction so that the absorber can be curved to be convex in the inward direction; at each of the middle portions, a side curve forming portion is formed along the lengthwise direction so that the absorber can be curved to be convex in the outward direction; an average total weight of the water absorbent polymer at the central portion and the pair of side edge portions (S L, S R) is smaller than an average total weight of the water absorbent polymer at the middle portions (M L, M R); and a thickness of the absorber in the central portion and the side edge portions is smaller than a thickness of the absorber at the middle portion. 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 (S L, S R) including a side edge of the absorber in the widthwise direction, and a pair of middle portions (M L, M R) which are positioned between the central portion and the side edge portions; at the central portion, a central curve forming portion is formed along the lengthwise direction so that the absorber can be curved to be convex in the inward direction; at each of the middle portions, a side curve forming portion is formed along the lengthwise direction so that the absorber can be curved to be convex in the outward direction; an average total weight of the water absorbent polymer at the central portion and the pair of side edge portions (S L, S R) is smaller than an average total weight of the water absorbent polymer at the middle portions (M L, M R); and a thickness of the absorber in the central portion and the side edge portions is smaller than a thickness of the absorber at the middle portion.
