1. A disposable worn article comprising: an absorbent body including two liquid-permeable non-woven fabric sheets bonded together at bonded portions in a predetermined pattern, and a plurality of liquid-absorbing granular particles, the granular particles placed between the two liquid-permeable non-woven fabric sheets and separately in each placement area of a plurality of placement areas partitioned from one another by the predetermined pattern, wherein the each placement area is one area that is surrounded by the bonded portions and excludes the bonded portions, the bonded portions are ultrasonically-bonded portions formed by applying an ultrasonic energy to the two non-woven fabric sheets, and have a bonding strength such that the non-woven fabric sheets are not separated from each other at the bonded portions by a force that occurs when the granular particles absorb a bodily fluid to swell; and a non-liquid-permeable back sheet placed on a non-skin-contact surface of the absorbent body, wherein: a liquid-permeable sheet is placed so as to cover an entire surface of one of the two non-woven fabric sheets that is on a skin-contact surface side; an easily-breakable portion capable of being broken by a force that occurs when the granular particles absorb a bodily fluid to swell is formed linearly and intermittently in at least one or more of the plurality of placement areas on at least one of the two non-woven fabric sheets; and the easily-breakable portion is linearly formed by including a plurality of holes, slits and/or cuts formed intermittently on the at least one of the non-woven fabric sheets in each of the at least one or more of the plurality of placement areas.
