A method for forming a skin-contacting topsheet of disposable diaper with an elastic opening, wherein the opening 16 formed in the skin-contacting topsheet of a disposable diaper is elasticized along its whole peripheral edge and reinforced so as to form uniform gathers along the whole peripheral edge. The skin-contacting topsheet comprises a pair of sheet members overlapping side by side and having mutually opposed inner side edges, respectively, which are provided with cutouts so that each pair of mutually opposed cutouts form each opening, then elastic members are provided along halves of the opening's whole peripheral edge and these elastic members are covered with a part of the skin-contacting topsheet.
