Provided are an absorbent body and a device for producing the absorbent body that can form satisfactory connections while webs are conveyed at a high speed. The absorbent body is provided with: at least two sheets of nonwoven fabric overlapping each other connections (22, 23, 24) at which the nonwoven fabric sheets are connected together and an absorbent material that is disposed between the nonwoven fabric sheets at a small region (20) encircled by the connections (22, 23, 24). When seen in a direction perpendicular to a main surface of the nonwoven fabric sheets, a plurality of the connections (22, 23, 24) are formed with spaces therebetween on each side of imaginary polygons compartmentalizing the nonwoven fabric sheets and neighboring each other, and a protrusion is formed at least on a middle part of the sides common to the imaginary polygons neighboring each other. The connections are formed sequentially, the connections formed simultaneously are arranged in a row, the rows are parallel to each other, and the minimum number of connections (22, 23, 24) per row is at least 45% of the maximum number of connections (22, 23, 24) per row.
