Abstract
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.
