Abstract
A heater (1a) includes a support (10) made of an organic polymer and having a sheet shape, a heating element (20), and at least one pair of power supply electrodes (30) in contact with the heating element (20). The heating element (20) is a transparent conductive film made of a polycrystalline material containing indium oxide as a main component. In the heater (1a), the heating element (20) has a specific resistance of 1.4×10−4 Ω·cm to 3×10−4 Ω·cm. The heating element (20) has a thickness of more than 20 nm and not more than 100 nm.
