I n an absorbent article (1), an absorbent (4) i s configured o f an absorbent core (40) containing an absorbent material. The absorbent core (40) ， has high-weight parts (41) containing a relatively large amount o f the absorb ent material and low-weight parts (42) containing a relatively small amount o f the absorbent material and the high-weight parts (41) and the low-weight parts な(42) are alternately formed both in the lengthwise direction (X) and in the widthwise direction Ύ o f the absorbent article (1). I n the absorbent article (1), a groove (7) i s formed b y concaving a ：front face sheet (2) together with the absorbent core (40). The groove (7) i s at least formed o f a row o f two high- 一- weight parts (41) and (41) and one low-weight part (42), said low-weight part (42) being positioned between said two high-weight parts (41) and (41), that are aligned in the lengthwise direction ( or i n the widthwise direction (Y). A bottom wall part (71) constituting the groove (7) i s positioned closer t o the non -sKin -contact face (4b) side than the thickness direction center (Tc) o f the absorbent core (40).
