As the top sheet 2, a non-woven fabric obtained by treating a hydrophobic non-woven fabric with a hydrophilic agent or a hydrophilic non-woven fabric formed by fibers kneaded with a hydrophilic agent is used. Instead of these nonwoven fabrics, a thermoplastic synthetic resin film having openings may be used.

As the back sheet 3, a synthetic resin film or a laminate sheet of a synthetic resin film and a hydrophobic nonwoven fabric is used. The core 4 is a mixture of fluff pulp and superabsorbent polymer particles, is compressed to a required thickness, and is entirely covered with a liquid-permeable sheet such as tissue paper.

Although not shown, the release area 17 is formed inside the tape fastener 14 itself, adjacent to the engagement area V, or formed independently of the main body 1A and the tape fastener 14. A release piece may be used. When the engagement area V is one of the hook member and the loop member of the mechanical fastener, it goes without saying that the release area is unnecessary.

Although the above description relates to a disposable diaper, the present invention can be applied to a diaper cover and the like.

[0039]

According to the wearing article according to the present invention, the tab of the tape fastener extends outward to intersect the outer end of the tape fastener. It is easy to engage and disengage the release area and the receiving area. Also, when the tab is pinched with a fingertip, there is an obstacle due to the fingertip touching the engagement area, for example, when the engagement area is formed of an adhesive, the fat of the finger adheres to the adhesive area. When the adhesive strength is reduced or the engagement area is formed by the hook member of the mechanical fastener, there is no trouble such as giving an unpleasant stimulus to the finger.

When the engaging area is engaged with the receiving area, for example, while the tab is held between the index finger and the thumb,
In other words, without inverting the index finger or the middle finger as in the prior art, or once separating the index finger and the thumb holding the tab from the tab, press the engagement area against the receiving area with those fingers. It can be engaged and is very simple.
