Abstract
A heating body, in which a heat-generating composition that generates heat in the presence of air, is accommodated in a bag body formed by heat sealing a one-surface side laminated base material including a first base material and a second base material, and a covering material, at a peripheral edge portion thereof. The first base material has a nonwoven fabric layer and a heat sealable resin layer; and the second base material is a sheet in which an olefin-based nonwoven fabric layer and a resin film are laminated using an olefin-based resin. The first base material and the second base material are capable of forming a space into which a body part can be inserted or held. The heat sealable resin layer and the nonwoven fabric layer are bonded together, and the resin film of the second base material and the covering material are bonded together.
