Abstract

Provided is an absorbent article capable of suppressing back leakage when the wearer is lying on his back. The absorbent article (1) has a first curved portion (41) on the rear side of the center of the wing portion (3) in the front-back direction (L) and on the front side of the rear end edge of the absorbent core along the extending in the width direction (W); and a second curved portion (42) located behind the first curved portion (41) and extending along the width direction (W). The absorbent article (1) has: a first region (R1) adjacent to the first curved portion (41) in front of the first curved portion (41); a second region (R2) adjacent to the second curved portion The rear of (42) is adjacent to the 2nd curved portion (42); and an intermediate region (R3), which is located between the 1st curved portion (41) and the 2nd curved portion (42) in the front-rear direction (L). The basis weight of the absorbent in the middle region (R3) is lower than that of the absorbent in the first region (R1) and lower than that of the absorbent in the second region (R2). The length in the front-rear direction (L) of the middle region (R3) is longer than the thickness of a portion of the absorber (30) adjacent to the first curved portion (41) in the first region (R1).

Description

technical field [0001] The present invention relates to absorbent articles such as sanitary napkins. Background technique [0002] Absorbent articles for night use are used with the wearer lying down, and are used for a longer period of time than absorbent articles for daily use.

[0003] The absorbent article of Patent Document 1 has: a discharge part facing part arranged to face a wearer's liquid discharge part; and a rear part arranged on the back side of the discharge part facing part. A plurality of high-density portions and low-density portions extending in the width direction are formed in a portion located in the rear portion of the absorber. In the absorbent article of Patent Document 1, when the bodily fluid flows to the rear, the high-density portion with a relatively high density retai...
