Abstract
An absorbent body forming satisfactory connections while webs are conveyed at a high speed includes at least two sheets of nonwoven fabric overlapping each other; connections at which the nonwoven fabric sheets are connected together; and an absorbent material disposed between the nonwoven fabric sheets at a small region encircled by the connections. When seen in a direction perpendicular to a main surface of the nonwoven fabric sheets, a plurality of the connections is formed with spaces therebetween on each side of imaginary polygons compartmentalizing the nonwoven fabric sheets and neighboring each other, and the connection is formed at least on a middle part of the sides common to the imaginary polygons neighboring each other. The connections are formed sequentially, and simultaneously arranged in a row parallel to each other, and the minimum number of connections per row is at least 45% of the maximum number of connections per row.
