Abstract

An absorbent article having a plurality of granular particles placed between two liquid-permeable non-woven fabric sheets, the article including: a high-strength bonded portion formed in a loop-shaped pattern on the article such that the two non-woven fabric sheets are not separated even if the granular particles swell to thereby apply a separating force to a bonded position between the two non-woven fabric sheets; and a low-strength bonded portion formed in an inner area surrounded by the high-strength bonded portion such that the two non-woven fabric sheets are separated from each other at a bonded position when the granular particles swell to thereby apply a separating force to the bonded position between the two non-woven fabric sheets.
