To provide an absorber that can secure sufficient absorption capacity even if a thickness is reduced, that is less likely to swell even if excrement is absorbed and that is flexible and excellent in shape retention.SOLUTION: An absorbent core 2 has a first core 3 and a second core 4 thinner than the first core 3. The first core 3 is interposed between a core wrap sheet 5 and the second core 4. The second core 4 includes two base sheets 4S opposite each other and a water absorbent polymer interposed between the base sheets 4S, and both the sheets 4S are bonded together by an adhesive. One or more pairs of joint portions 6 where the core wrap sheet 5 and the second core 4 are directly joined without interposing the first core 3 are present at least on either both sides in a longitudinal direction X or both sides in a lateral direction Y with the first core 3 between them. A portion sandwiched between the pair of joint portions 6 in the first core 3 is compressed in a thickness direction by the core wrap sheet 5 and the second core 4.SELECTED DRAWING: Figure 1 【課題】厚みを薄くしても十分な吸収容量を確保することができ、且つ排泄物を吸収しても膨潤しにくく柔軟で保形性に優れる吸収体を提供すること。【解決手段】吸収性コア２は、第１コア３と該第１コア３よりも厚みが薄い第２コア４とを有する。第１コア３は、コアラップシート５と第２コア４との間に介在配置される。第２コア４は、相対向する２枚の基材シート４Ｓと、両シート２Ｓ間に介在配置された吸水性ポリマーとを含み、両シート４Ｓどうしは接着剤によって互いに接合されている。第１コア３を挟んで縦方向Ｘの両側及び横方向Ｙの両側のうちの少なくとも一方の両側に、コアラップシート５と第２コア４とが第１コア３を介在させずに直接接合された接合部６が、一組以上の対となって存在している。第１コア３における接合部６の対に挟まれた部分が、コアラップシート５と第２コア４とによって厚み方向に圧縮された状態となっている。【選択図】図１
