A filter device that removes a noise current generated by an inverter includes a first filter capacitor that is provided in parallel to a direct-current unit of the inverter, a first filter reactor that is provided between a high-potential side of the first filter capacitor and an overhead line that is a power supply source of direct-current power, and a series circuit unit in which a fuse serving as a circuit disconnecting unit that is disconnected when a current larger than a rated current flows therein, a second filter reactor serving as an inductance element, and a second filter capacitor serving as a capacitance element are connected in series, where one end of the series circuit unit is connected to a low-potential side of the first filter capacitor and one end of the first filter reactor is connected to the series circuit unit.
