Abstract

A shorts type disposable diaper includes a body having a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent member interposed between the topsheet and the backsheet. The body includes a stomach-side portion which is located on the stomach side of a diaper wearer when the diaper is worn, a back-side portion which is located on the back side of the wearer when the diaper is worn, and a crotch portion which is located between the stomach-side portion and the back-side portion. The body has a pair of first expansible side panels, each of the first expansible side panels being affixed to each longitudinal side of the stomach-side portion and a pair of second expansible side panels, each of the second expansible side panels being affixed to each longitudinal side of the back-side portion. The first expansible side panels of the stomach-side portion are affixed to the second expansible side panels of said back-side portion to thereby define a waist opening portion, a pair of leg opening portions and a body-surrounding portion located around the wearer's body when the diaper is worn. Elastic members are arranged on an area adjacent to the waist opening portion and on the body-surrounding portion in the stomach-side and back-side portions. A substantially continuous gather is formed along an entire periphery of the diaper through the stomach-side portion, the back-side portion and the first and second expansible panels.
