Abstract
The animal waste collection sheet is planar and is consisted of a top sheet which is liquid permeable, a back sheet which is liquid impermeable and an absorbent sheet disposed between the top sheet and the back sheet. The top sheet has a high fiber density region in a thickness direction thereof, with a fiber density higher than an average fiber density of the top sheet, at least in a part of a side facing the absorbent sheet. The average fiber density is preferably in the range of 0.005 to 0.20 g/cm3, and a fiber density of the high fiber density region is preferably in the range of 0.007 to 0.25 g/cm3.
