PROBLEM TO BE SOLVED: To provide an absorber which includes a highly absorptive polymer of high absorption performance and yet achieving an excellent wet-time shape retention property to thereby enable an excellent body fluid repetitive absorption property.SOLUTION: The present invention provides an absorber 17, including: a laminated absorbent core 21 which is laminated with a first absorbent core layer 18, an intermediate layer 19, and a second absorbent core layer 20 in this order, with a highly absorptive polymer included therein； and a core-wrap sheet 26. A first core-wrap sheet portion 24 located on one side from a center plane Tc in the thickness direction has a water-absorbent nonwoven fabric containing water-absorbent fibers having a fiber length of 25 mm or more entangled with each other. The absorber 17 has joining portions 29 at which the intermediate layer 19 and the first core-wrap sheet portion 24 are joined. The wet-time elongation of the water-absorbent nonwoven fabric is larger than the dry-time elongation. The wet-time tensile strength is lower than the dry-time tensile strength. The intermediate layer 19 is a heat-sealed nonwoven fabric having a wet-time elongation and tensile strength in a range of 90% or more and 110% or less of the dry-time elongation and tensile strength.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2020,JPO&INPIT【課題】本発明は、湿潤時形態保持性に優れるとともに、高吸収性ポリマーの吸収性能が高く、体液繰返し吸収性に優れる吸収体を提供することを目的とする。【解決手段】本発明は、第１の吸収コア層１８、中間層１９、及び第２の吸収コア層２０がこの順に積層された、高吸収性ポリマーを含む積層吸収コア２１と、コアラップシート２６とを有し、厚さ方向中心面Ｔｃよりも一方面側に位置する第１のコアラップシート部分２４は、互いに交絡した繊維長２５ｍｍ以上の吸水性繊維を含む吸水性不織布を有し、吸収体１７は、中間層１９及び第１のコアラップシート部分２４が接合している接合部２９を有し、吸水性不織布の湿潤時の伸度が乾燥時の伸度よりも大きく、湿潤時の引張強度が乾燥時の引張強度よりも低く、中間層１９が、湿潤時の伸度及び引張強度が、乾燥時の伸度及び引張強度の９０％以上１１０％以下の範囲内である熱融着不織布である、吸収体１７を提供する。【選択図】図２
