Provided is a failure determination device including: a storage medium that stores a command capable of being read by a computer; and a processor connected to the storage medium, wherein the processor executes the command capable of being read by the computer, to thereby acquire rotation angle data indicating a rotation angle of a rotor, voltage phase data indicating a phase of a voltage applied to a rotating electrical machine, angular velocity data indicating an angular velocity of the rotor, direct-current voltage data indicating a direct-current voltage supplied to an inverter that supplies electric power to the rotating electrical machine, and current data indicating a current supplied to the rotating electrical machine, generate current expectation value data indicating an expectation value of the current supplied to the rotating electrical machine using the rotation angle data, the voltage phase data, the angular velocity data, and the direct-current voltage data, and determine, in a case where the inverter is controlled by one-pulse control, whether at least one of a signal line connected to a switching element and a conducting wire for supplying electric power to the rotating electrical machine has failed on the basis of the current expectation value data and the current data.
