PROBLEM TO BE SOLVED: To provide an absorber capable of preventing the peeling between a reservoir and a coating layer that may occur under use environment (particularly under wet conditions), the absorber having the reservoir for temporarily reserving liquid, an absorbent core for absorbing the liquid reserved in the reservoir, and the coating layer for coating the absorbent core, and to provide an absorbent article with the same.SOLUTION: An absorber (4) has a reservoir (41) for temporarily reserving liquid, an absorbent core (42) for absorbing the liquid reserved in the reservoir (41), a coating layer (43a) for coating the surface of the reservoir side of the absorbent core (42), and an integration part (44) for integrating the reservoir (41) and the coating layer (43a). The reservoir (41) contains a cellulosic absorbent fiber, and a thermoplastic resin fiber containing an unsaturated carboxylic acid, an unsaturated carboxylic acid anhydride or those mixtures as a monomer component. The absorbent core (42) contains a superabsorbent polymer material, and the coating layer (43a) provides the absorber (4) containing the cellulosic absorbent fiber.COPYRIGHT: (C)2015,JPO&INPIT【課題】液体を一時的に貯留する貯留層と、貯留層に貯留された液体を吸収する吸収性コアと、吸収性コアを被覆する被覆層とを有する吸収体であって、使用環境下(特に湿潤状態)において生じるおそれがある貯留層と被覆層との剥離を防止可能な吸収体、並びに、これを備えた吸収性物品を提供する。【解決手段】液体を一時的に貯留する貯留層(41)と、貯留層(41)に貯留された液体を吸収する吸収性コア(42)と、吸収性コア(42)の貯留層側の面を被覆する被覆層(43a)と、貯留層(41)及び被覆層(43a)を一体化する一体化部(44)とを有する吸収体(4)であって、貯留層(41)が、セルロース系吸水性繊維と、不飽和カルボン酸、不飽和カルボン酸無水物又はそれらの混合物をモノマー成分として含む熱可塑性樹脂繊維とを含有し、吸収性コア(42)が、高吸水性ポリマー材料を含有し、被覆層(43a)が、セルロース系吸水性繊維を含有する、吸収体(4)を提供する。【選択図】図4
