The invention relates to the field of sanitation supplies, and provides a three-dimensional anti-leakage paper diaper which can solve the defects of poor anti-leakage effect and poor three-dimensional structure of the conventional paper diapers. The three-dimensional anti-leakage paper diaper includes a paper diaper body; it is defined that the paper diaper has a longitudinal direction in the length direction of the paper diaper and a horizontal direction in the width direction of the paper diaper; the paper diaper body includes a liquid penetrating surface layer, a non-liquid penetrating surface layer and an absorption member arranged between the liquid penetrating surface layer and the non-liquid penetrating surface layer; three-dimensional anti-leakage layers are arranged on two horizontal sides of the liquid penetrating surface layer; it is defined that the paper diaper has a front waist region, a crotch region and a front waist region in the longitudinal direction; the two horizontal side edges of the liquid penetrating surface layer cover the absorption member downward and inward; a non-woven fabric or toilet paper having two horizontal side edges partly covering the absorption member upward and inward is arranged between the absorption member and the non-liquid penetrating surface layer; and rubber bands are arranged on two horizontal side edges of the absorption member.
