Absorbent article and manufacturing apparatus for absorbent article

摘要

A compressed portion 50 is formed in the absorbent article 1 by compressing the absorber 30 through a compression process. The compressed portion 50 has a top-surface groove 51 formed on the skin-contact-surface side, and a back-surface groove 52 formed on the clothing-contact-surface side. A bottom portion 51B of the top-surface groove 51 is flat. Since the recessed portions 54A and 54B are formed in the bottom portion 52B of the back-surface groove 52 through the compression process, a compression part DL where the density of the absorber 30 is increased more than in an uncompressed portion and high compression parts DH where the density of the absorber 30 is increased more than in the compression part are formed in the bottom portion 51B. Thus, the absorbent article 1 can be permeate into by a thick liquid, and is more likely to absorb liquid.
