Abstract: A disposable wearing article includes a partition provided in a front half of a crotch region divided by a transverse centerline bisecting a longitudinal dimension of the article so that the partition extends in the transverse direction on a topsheet. During use of the article, the partition curves in the transverse direction so as to describe a generally circular arc which is convex upward above the topsheet. The partition is thus spaced upward from the topsheet and the wearer's genital organ in contact with an outer surface of the partition is also spaced from the topsheet. In this way, the genital organ is protected from soiling with loose passage.
