PROBLEM TO BE SOLVED: To provide an underpants type clothing article easy to open, easy to wear, hardly forming bedsore on a wearer while wearing, easy to see a fusion part of a side seal part, and easy to tear off after using.SOLUTION: An underpants type clothing article 1 is formed with a pair of side seal parts 4 by joining in a principal-rafter-like form a marginal part A1 of an exterior body 3 of a front body F and a marginal part B1 of an exterior body 3 of a back body R. The side seal part 4 is formed by joining the marginal parts A1 and B1 by the irradiation of laser beam in a continuous linear fusion part 40 extending in a direction in which the side seal parts 4 extend. The side seal part 4 has a shape in which an outer edge 4a of the fusion part 40 is recessed toward the inner side, in a cross section orthogonal to a direction in which the side seal part 4 in a natural state extends, and one of the end parts of an end part 40F on the front body F side and an end part 40R on the back body R side of the fusion part 40 projects outward. |
