  • Patent number: 11938007
    Abstract: A pet diaper includes: a top sheet; a back-surface sheet; an absorbent core disposed between the top sheet and the back-surface sheet; a tail hole portion including a hole body through which a tail of a pet is inserted; and an upright leak-proof gather including a rising portion including a contraction portion in which a leak-proof elastic member is disposed in a stretched state in a longitudinal direction, and a lateral fixed portion that is disposed away from the rising portion toward a lateral outer side and that functions as a rising fulcrum of the rising portion. The tail hole portion is disposed at a position that is away from an end edge of the absorbent core on the rear side toward the rear side. The contraction portion is disposed straddling a region between the tail hole portion and the absorbent core.
