Abstract: A heat generating body (11) includes a polyimide resin film base material (12), a metal nanowire layer (14) arranged in a planar manner along one side of the polyimide resin film base material (12), and an electrode (5) connected electrically to the metal nanowire layer (14). The electrode (5) is connected electrically to the metal nanowire layer (14) via a polythiophene resin film layer (18). The heat generating body (11) also includes a triacetate resin film layer (13) arranged on the side of the polyimide resin film base material (12) on which the metal nanowire layer (14) is provided and formed of triacetate resin as an insulating material. The heat generating body (11) also includes a spacer portion (16) arranged between the layer (14) and the layer (13) and capable of forming an enclosed space (17) between the layer (14) and the layer (13).
