摘要： To provide an absorber that has a high absorption speed, is unlikely to cause a liquid to remain on a skin-contacting surface, has excellent dry feeling, and is unlikely to cause excreted body fluid to return, and a water-absorbent resin powder that can be suitably used in the absorber. A water-absorbent resin powder of the present invention is characterized by meeting the following requirements (a) to (d): (a) a bulk density: 0.45 g/ml to 0.62 g/ml; (b) an absorption speed by a vortex method: 20 seconds to 50 seconds; (c) a liquid-passing speed under load: 10 seconds or less; and (d) a moisture absorption blocking ratio: 5% or less. An absorber of the present invention uses the water-absorbent resin powder of the present invention. An absorbent article of the present invention includes the absorber of the present invention.

摘要： To provide an absorbent article that has a high absorption speed, is unlikely to cause a liquid to remain on a skin-contacting surface, has excellent dry feeling, and is unlikely to cause excreted body fluid to return. The present invention provides an absorbent article comprising an absorber composed of at least one absorbent layer, wherein a water-absorbent resin powder meeting the following requirements (a) to (d) is disposed in an uppermost layer of the absorber: (a) a bulk density: 0.45 g/ml to 0.62 g/ml; (b) an absorption speed by a vortex method: 20 seconds to 50 seconds; (c) a liquid-passing speed under load: 10 seconds or less; and (d) a moisture absorption blocking ratio: 5% or less.

摘要： First welds (511) each slope downward toward the outer side in the width direction. Second welds (521) each slope downward toward the outer side in the width direction. Third welds (531) each slope upward toward the outer side in the width direction. When one first weld (511), one second weld (521), and one third weld (531) that are adjacent to one another in the width direction form one weld group (54), each weld group (54) is configured such that the upper end of the third weld (531) is located downward of the upper end of the second weld (521), the upper end of the second weld (521) is located downward of the upper end of the first weld (511), the lower end of the second weld (521) is located downward of the lower end of the first weld (511), and an extension line extending outward in the width direction from the second weld (521) intersects with the third weld (531). This allows the side seals (5) to be torn off with ease from the upper end toward the bottom.
