A heating apparatus of a window glass of a vehicle comprises a heater which generates heat for melting ice adhering to an imaging glass part including a whole part of a corresponding part within a window glass which corresponds to an imaging range of an onboard camera. The heater heats the imaging glass part in such a manner that an amount of heat per unit area applied to a specific part of the imaging glass part on an upstream side in a liquid flowing direction which is a direction in which the liquid flows on a side surface outside a vehicle cabin of the imaging glass part becomes larger than an amount of heat per unit area applied to a part of the imaging glass part on an downstream side with respect to the specific part in the liquid flowing direction.
