Abstract
A photographing apparatus for vehicle includes a control device which is configured to execute either a first processing or a second processing when a specific condition is satisfied until when a predetermined period of time elapses from start time of the predetermined period of time. The specific condition is satisfied when magnitude of a heat generation amount determination factor deviates from magnitude of the heat generation amount determination factor at the start time of the predetermined period of time by a predetermined value or more. The first processing is a processing to stop applying voltage to heating means until when the predetermined period of time elapses. The second processing is a processing to change a voltage application time based on magnitude of the heat generation amount determination factor at the time when the specific condition is satisfied.
