Abstract
Provided are a heat generation sheet and a method of fabricating the same. The heat generation sheet includes: a base comprising first and second sides; a heat generation layer which is formed in at least one region of the first side of the base and in which a plurality of conductive nanoparticles are physically necked; a protective layer protecting the heat generation layer; and an electric feeding part supplying power to the heat generation layer. The heat generation layer is formed by coating and heat treating a nanoparticle dispersion solution.
