ABSTRACT:
A disposable diaper includes a backsheet comprising an elastic inner layer and an inelastic outer layer. The elastic inner layer, in a transversely stretched state, is joined to the inelastic outer layer at a plurality of intermittently disposed spots. The spots are lined up to form a series of imaginary lines disposed on a bias between the longitudinal and transverse directions of the disposable diaper. In each of areas between the spots, defined by a plurality of intersecting imaginary lines that pass through a plurality of the spots that are closely arranged in succession, the inelastic outer layer is free to separate from the elastic inner layer upon contraction (relaxation) of the elastic inner layer, and thereupon the outer layer forms a plurality of longitudinal pleats. The pleats, formed by relaxing the transversely stretched inner layer, are disposed in a direction that is substantially normal to the direction of stretching.
