Abstract

A disposable wearing article 1A comprises a liquid-pervious topsheet 2, a liquid-impervious backsheet 3 and a liquid-absorbent panel 4 interposed between the top- and backsheets 2, 3. The backsheet 3 is formed by a breathable and hydrophobic first fibrous nonwoven fabric layer f2 underlying the panel 4, a breathable and liquid-impervious plastic film f4 underlying the first fibrous nonwoven fabric layer f2 and a breathable and hydrophobic second fibrous nonwoven fabric layer f3 underlying the film f4. In a zone occupied by the panel 4, the first fibrous nonwoven fabric layer f2 is intermittently joined to an under surface of the panel 4 by means of a hot melt adhesive and the film f4 is intermittently joined to the first fibrous nonwoven fabric layer f2 by means of the hot melt adhesive.
