A wiper drive device includes: a wiring connected to a wiper motor; a drive element configured to apply a voltage to the wiper motor through the wiring by being turned on so as to rotate the wiper motor; a braking element configured to brake the wiper motor by being turned on when the drive element is turned off so as to flow a current corresponding to a rotational energy of the wiper motor; and a determination unit configured to determine that the braking element is abnormal when a time period from when the wiper motor is braked to when an electric potential of the wiring becomes equal to or less than a predetermined threshold potential is longer than a predetermined value which is the time period in case where the braking element is normal.
