    摘要： A pants-type disposable diaper (1) includes a pair of strip projecting parts (13) projecting laterally from a line of connection between front and rear parts located respectively on the belly and back sides of a wearer, a first waist elastic member (443) joined to a first waist region (407) that is an upper part of a waist region (406) extending along a waist opening, and a second waist elastic member (444) joined to a second waist region (408) that is a lower part of the waist region (406). In a state in which an outer covering sheet (4) is elongated in a right-left direction, a first unit contractile force that is a contractile force in the right-left direction per unit width of the first waist region (407) in an up-down direction is smaller than a second unit contractile force in the second waist region (408). Accordingly, it is possible to suppress cutting in of the upper end portions of the pair of strip projecting parts (13) into the skin of the wearer and to prevent the disposable diaper (1) from slipping off in the up-down direction when being worn.

    摘要： Concave portions filled with particles of high-absorbent resin are arranged on an outer side surface of a cylinder part in a circumferential direction. When each concave portion passes an ejection start position lying posterior to the lowermost portion in a rotation direction, particles are ejected along a tangent line of the side surface at the ejection start position. A sheet conveying roller is located near the above lowermost portion. Annular grooves facing concave portions are formed on an outer side surface of the roller along a circumferential direction. The roller conveys a sheet member along its side surface so that the sheet member passes near the above lowermost portion. In the sheet member, groove portions corresponding to the annular grooves are formed. Since the tangent line intersects with the side surface of the roller, it is possible to eject particles into the groove portions and reduce scattering of particles.
