1. A vehicle imaging apparatus comprising:
an imaging device capable of imaging an imaging side thereof;
a transparent heater provided at least in a range of an angle of view of the imaging device at the imaging side of the imaging device, generating heat by being energized, and heating the imaging side of the imaging device; and
a resistance member provided at an electrical circuit that includes the heater, and generating heat by being energized, an electrical resistance value of the resistance member being increased along with increase in temperature of the resistance member due to the heat generation such that a current value of current that flows to the heater is decreased,
wherein the resistance member is separate from a transparent plate, and the transparent heater is disposed at the transparent plate.
