The present invention relates to a warming tool () in which a heat generating element () is held between a topsheet () that faces a heating target and a backsheet () that is located on a side away from the heating target, and a method for manufacturing the same. The heat generating element () has a first sheet () arranged opposing the topsheet (), a second sheet () arranged opposing the backsheet (), and a heat generating portion () sandwiched between the first sheet () and the second sheet (). In the warming tool (), a perfume () and an adhesive () are arranged between the second sheet () and the backsheet (), and a region in which the adhesive () is arranged and a region in which the perfume () is not arranged overlap each other in a plan view. In the manufacturing method, the perfume is added to a surface of the second sheet () that is planned to oppose the backsheet (), or to a surface of the backsheet () that is planned to oppose the heat generating element (), and the heat generating element () is held such that the backsheet () and the second sheet () oppose each other.

A absorbent member manufacturing method of the invention is a method for manufacturing an absorbent member () including synthetic fibers (). The method involves: a transporting step of transporting a plurality of sheet fragments () including synthetic fibers () to an accumulating depression () by using a duct; an accumulating step of accumulating, in the accumulating depression (), the plurality of sheet fragments () transported in the transporting step, and forming an accumulation (') which is a constituent member of the absorbent member (); and a pressing step of pressing the accumulation (&#x2032;) over its entirety in the thickness direction.

An absorbent member manufacturing method of the present invention is a method for manufacturing an absorbent member () for an absorbent article and including synthetic fibers () and hydrophilic fibers (). The method involves: a transporting step of transporting the hydrophilic fibers () and a plurality of sheet fragments () to an accumulating depression () by using a duct (); an accumulating step of accumulating, in the accumulating depression (), the plurality of sheet fragments () and the hydrophilic fibers (), and obtaining an accumulation () which is a constituent member of the absorbent member (); and a depression forming step of forming a depression () in the accumulation () by applying pressure to a portion thereof. In the transporting step, the sheet fragments () and the hydrophilic fibers () are brought into contact with one another in an airflow created inside the duct (), and the sheet fragments () and the hydrophilic fibers () are transported by the airflow in a dispersed and airborne state in which the sheet fragments and the hydrophilic fibers are mixed.

A rotating drum () has a collecting/stacking recess () in the outer peripheral surface thereof, and includes: a drum body (); and an air-permeable porous member () that forms the bottom surface (A) of the collecting/stacking recess (). The porous member () is sandwiched between: an outer shaping member () arranged so as to oppose the bottom surface (A); and an inner shaping member () arranged between the porous member () and the drum body (). Both the shaping members () are arranged so as to overlap the porous member (). Each shaping member () has a recess-bottom-surface corresponding section (A,A) that overlaps the bottom surface (A) of the collecting/stacking recess () in a planar view thereof, and that is constituted by: a plurality of openings () that penetrate the recess-bottom-surface corresponding section (A,A) in the thickness direction; and an opening defining section () that partitions and forms the openings (). The opening defining section () of the inner shaping member () corresponds to the opening defining section () of the outer shaping member ().
