摘要： Provided is a heating body that enables high-speed production using a conventional rotary heat-sealing roll, has a wearing portion with sufficient strength to use by inserting a hand or the like, thereby being used safely and conveniently, and can be worn on the body or the like without being adhered thereto, and a method for producing the same. An example of one aspect of the present invention is 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 comprising a first base material and a second base material, and a covering material, at a peripheral edge portion thereof, characterized in that: the first base material has one surface being a nonwoven fabric layer and the other surface being a heat sealable resin layer; 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, in a part surrounded by the peripheral edge portion; and in a heat sealed part of the bag body peripheral edge portion, the heat sealable resin layer of the first base material and the nonwoven fabric layer of the second base material are bonded together, and the resin film of the second base material and the covering material are bonded together; as well as a method for producing the same.
