Abstract
The present invention provides a disposable wearing article which prevents a position shift of a front waist region without a part of a front waist region receding in a concave portion of the abdomen of the wearer. A plurality of linear front waist elastics contractible in a lateral direction is disposed in a front waist region of a disposable wearing article. The front waist elastics have (include) a first elastic positioned adjacent to an outer side of a front-end edge of a liquid absorbent core in a vertical direction, a second elastic positioned adjacent to an inner side of the front-end edge in the vertical direction, and a third elastic positioned adjacent to an inner side of the second elastic in the vertical direction. A contractile force of the first elastic and the second elastic is weaker than a contractile force of the third elastic.
