A leakage-preventing unit 50 of an absorbent article 1 is formed by elastic members 51 and sheets 52. The leakage-preventing unit 50 includes a central region C and a pair of end unit regions S positioned outside a longitudinal direction L from the central region C. The elastic members 51 include a fixed unit 51A fixed to the sheet 52 in a state when the elastic members 51 extend in the longitudinal direction L and a free end 51 B positioned outside the longitudinal direction L from the fixed unit 51A, which is not fixed to the sheet 52. The end unit regions S includes a joint processing unit 53A in which a joint process for joining the portions where the sheets 52 face each other is performed and a non-joint processing unit 53B in which the joint process is not performed. The free end 51 B is arranged in the non-joint processing unit 53B.
