    Abstract: A configuration in which an upper auxiliary layer of an absorber includes a super absorbent nonwoven fabric having a surface exposed on an uppermost surface of the absorber and having a Klemm water absorptiveness of 100 mm or more, first super absorbent polymer particles adjacent to a back surface of the super absorbent nonwoven fabric. The main absorption layer of the absorber is a cell absorbing sheet including second super absorbent polymer particles contained in the cells arranged at intervals. A convex bulging upward is formed at each cell in an upper sheet. The first super absorbent polymer particles are fixed to the upper surface of the upper sheet. An adhesion amount of the first super absorbent polymer particles on the upper surface of the upper sheet increases from the top of a convex toward the bottom of a valley between a convex and a convex adjacent each other.

    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 ΔE 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 rising portion of a rising gather includes a main region having a first part extending toward the center in the width direction, a second part extending outward in the width direction from the tip of the first part, in the middle of the front-back direction including a crotch portion, and a support region composed of only a third part extending toward the center in the width direction, between the main region and a back fallen portion. The main region has a first gather elastic member attached to a tip end of the second part along the front-back direction. The support region has a second gather elastic member attached to the tip end of the third part along the front-back direction. The base edge side of the third part is a non-stretchable portion, and the third part has a layer that follows the second part of the main region.
