In a pants-type diaper, two folding lines which are extensive in a longitudinal direction and which are spaced in a widthwise direction are formed at an absorber that is disposed in a crotch region A of the pants-type diaper. A plurality of compression lines which are extensive in the widthwise direction and which are spaced in the longitudinal direction are formed in a predetermined region of the absorber. An angle formed by a centerline in a widthwise direction in the compression lines and the widthwise direction is configured so as to be included in a range of 0 degrees to 45 degrees. Two of the compression lines are adjacent to each other in the longitudinal direction are configured so as to approach at a predetermined portion.
