Abstract

A disposable diaper includes barrier cuffs 19 around wearer's legs. Each of the barrier cuffs longitudinally extends on an inner surface of the disposable diaper 1 and includes a supporting wall section 16 adapted to rise on the inner surface of the diaper and a sealing surface zone 20 which includes a first overhead section 17 extending inwards from the supporting wall section 16 and a second overhead section 18 extending outwards from the supporting wall section 16. A first elastic member extending along an inner edge of the sealing surface zone 20 in operative association with the first overhead section 17 has an elongation stress higher than that of a second elastic member extending along an outer edge of the sealing surface zone 20 in operative association with the second overhead section 18. The barrier cuffs 19 thus constructed provide a good fit around a wearer's legs to prevent body fluids from leaking.
