The present invention provides a disposable wearing article adapted to inhibit sweating and an uncomfortable stuffiness. Front and rear waist regions 6, 7 of a disposable wearing article have inner surfaces thereof at least partially formed of elastic sheets 37, 38. The elastic sheets 37, 38 are made of a mixture of elastic fibers and inelastic fibers and formed with ridges and grooves. The elastic sheets have a thickness in the ridges repetitively reduced and restored as the elastic sheets repeat elastic stretch and contraction in the waist circumferential direction.
