A photographing device for a vehicle includes: an imaging element (30) configured to receive a photographing beam passing through a beam transmission section (85a) of a window section (85); a heater (47A, 47B) constituted by a heating wire; a section to be heated (40A, 40B, 40C, 40D) to which the heater (47A, 47B) is fixed, the section to be heated (40A, 40B, 40C, 40D) being opposite to an inner side surface of the beam transmission section (85a); a switch element (89) configured to switch electrical connection state to the heater (47A, 47B); and a current limiting element (52, 91) disposed at the section to be heated (40A, 40B, 40C, 40D) and being configured such that current flowing through the heater (47A, 47B) becomes zero or is reduced when the electric circuit is short-circuited such that power is supplied to the heater while bypassing the switch element (89) and a temperature of the current limiting element (52, 91) become equal to or higher than a predetermined value.
