Abstract
A pants-type wearing article in which at least a central segment of a crotch region has a desired degree of flexibility and a portion of a crotch region close to a front waist region has a desired degree of tensile strength. The front and rear waist regions and at least a portion of the crotch region close to the front waist region define a multilayer zone composed of a base sheet and a front waist sheet layered with each other and a central segment of the crotch region defines a monolayer zone formed of the base sheet alone. The multilayer zone includes corners each surrounded by a boundary, an inner end of the front waist region, a joint region in which a liquid-absorbent structure is bonded to a chassis and a concave lateral edge of the crotch region and the boundary extends across the joint region.
