8. A pet diaper having a lateral direction along a waistline direction of a pet and a longitudinal direction that is orthogonal to the lateral direction and extends in a direction connecting a stomach side and a rear side of the pet, the pet diaper comprising:
a main body portion comprising a top sheet, a back-surface sheet, and an absorbent core between the top sheet and the back-surface sheet, wherein
the main body portion includes an upright leak-proof gather and a tail hole that has a hole body portion through which a tail of the pet is to be inserted,
the leak-proof gather includes;
a rising portion configured to rise up;
a lateral fixed portion that is positioned away from the rising portion toward a lateral outer side of the pet diaper and that functions as a rising fulcrum of the rising portion; and
a longitudinal fixed portion that is positioned away from the rising portion toward the lateral outer side in the longitudinal direction and that functions as a rising fulcrum of the rising portion,

the rising portion of the leak-proof gather includes a contraction portion that has a leak-proof elastic member linearly extending in the longitudinal direction in a stretched state and not bonded to the back-surface sheet,
the tail hole is positioned on the rear side and away from an end edge of the absorbent core toward the rear side,
the contraction portion of the rising portion straddles a region of the pet diaper between the tail hole and the absorbent core,
the contraction portion of the rising portion is positioned in a hole side region of the pet diaper that extends from the tail hole toward the lateral outer side,
a rear-side end edge of the contraction portion is positioned on a rear side of an inner edge of the longitudinal fixed portion which is positioned rear side, and
the inner edge of the longitudinal fixed portion is positioned on the stomach side of a stomach edge of the hole side region.
