A wiper device including: a power supplying circuit including plural switching elements, the power supplying circuit supplying, to a wiper motor, voltage that has been converted in accordance with switching control of the plural switching elements; a temperature detecting section detecting a temperature relating to a temperature of at least one of the switching elements among the plural switching elements; a current detecting section detecting current flowing to any of the switching elements among the plural switching elements; and a control section that, in a case in which the current detected by the current detecting section exceeds a limit current at the temperature detected by the temperature detecting section, carries out switching control of the switching elements such that the voltage supplied to the wiper motor decreases.
