A windshield heating device includes: a heating wire that heats a first part of a windshield of a vehicle, the first part being located in front of a camera; a glass heating apparatus that heats a second part of the windshield, the second part including the first part; and a control unit that controls energization to the heating wire and the glass heating apparatus. The control unit is configured: to determine whether energization to the glass heating apparatus is performed when heating of the first part is requested; to control so that energization to the heating wire is performed when it is determined that the energization to glass heating apparatus is not performed; and to control energization to the heating wire so that an amount of energization to the heating wire is reduced when it is determined that energization to the glass heating apparatus is performed.
