1. An arc detection device comprising:
an obtainer that obtains a measurement result for a voltage applied to one target power supply line among a plurality of power supply lines to which power is supplied from a DC power source; and
a determiner that, based on a component of a specific frequency band in the measurement result for the voltage obtained by the obtainer, determines whether there is a possibility of an arc fault occurring in the plurality of power supply lines.
