Abstract
A heat conductivity from a heating body to a user's skin is improved to provide satisfactorily warm feeling to the skin of the user. A laminated heating body has a heating body and a cover sheet covering the heating body. The cover sheet defines at least one low temperature portion formed from a material having low heat conductivity and at least one high temperature portion formed from a material having high heat conductivity. The at least one low temperature portion and the at least one high temperature portion are formed separately on a surface of the cover sheet contacting with a user's skin.
