An underwater mobile body includes: a secondary battery; a detector that detects a remaining amount of electricity stored in the secondary battery; a power generation unit that uses natural energy to generate electricity with which the secondary battery is charged; and a transition unit that when the remaining amount of electricity detected by the detector decreases below a predetermined threshold, causes transition to a charge mode in which the secondary battery is charged.
