Abstract
A film heater includes a transparent conductive film, a first electrode, and a second electrode. The transparent conductive film includes a first heat generating portion, and a second heat generating portion. The first electrode includes a first connection portion, and a second connection portion. The first connection portion is connected to the first heat generating portion. The second connection portion is connected to the second heat generating portion and the first connection portion. The second electrode faces the first connection portion and is connected to the first heat generating portion and the second heat generating portion. Further, a length of a path of an electric current flowing through the second heat generating portion is shorter than a length of a path of an electric current flowing through the first heat generating portion. Also, an electrical resistance of the second connection portion is higher than that of the first connection portion.
