Disposable trunks type shorts comprising a pair of outer sheets (B1, B2) being surface-symmetric with each other across a virtual plane extending vertically, and a pair of inner sheets (A1, A2) disposed between the plane and the outer sheets and being surface-symmetric with each other; and having elastic members (10, 11) attached thereto such that they are butt-joined at side edge portions where the outer sheets (B1, B2) and the inner sheets (A1, A2) extend vertically while respectively overlapping on respective opposite sides of the plane, they are joined at the edge portion of a concaved notch portion where the inner sheets (A1, A2) overlap each other on the plane to describe arcs from the upper edges toward the lower edges of the inner sheets (A1, A2), and they extend in a peripheral direction along the peripheral edge portion of a girth opening (12) of at least either of the outer sheets (B1, B2) and the inner sheets (A1, A2).
