Abstract

An absorbent article comprising an absorbent core. The absorbent core has: a front core section and a rear core section that are mutually facing in the longitudinal direction; and an intermediate coresection that is narrower than the front core section and the rear core section and is positioned between the front core section and the rear core section. The intermediate core section has: a high-basis-weight section having a higher basis weight than the front core section and the rear core section and being formed in the center in the width direction; and a low-basis-weight section having a lower basis weight than the front core section and the rear core section and being formed around the high-basis-weight section.

Description

technical field [0001] The present invention relates to absorbent articles such as sanitary napkins. Background technique [0002] When the sanitary napkin is used in the sleeping position, liquid tends to leak to the back or the like due to a gap between the sanitary napkin and the wearer. Therefore, in absorbent articles such as sanitary napkins, there is known a technique in which an absorbent core having a protrusion is provided in a central region in the width direction in order to improve fit to the wearer (see Patent Document 1). [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Laid-Open No. 2014-104093 Contents of the invention [0006] The technical problem to be solved by the invention [0007] An absorbent article of one aspect of the present invention includes an absorbent core. [0008] The absorbent core has: a front core and a rear core opposed to each other in the length direction; The width of the pa...
