PROBLEM TO BE SOLVED: To improve resistance in a system against a failure etc., by multiplexing a power management device, and to achieve efficient equipment control using a plurality of power management devices. SOLUTION: The power management device includes: an other device confirmation part which confirms the presence of other power management device under operation for managing same electronic apparatus; an attribute recognition part which, when it is confirmed by the other device confirmation part that (N-1) (N≥2) power management devices are operating, recognizes an attribute of one prescribed device as a master device, and recognizes attributes of remaining (N-1) devices as slave devices, in N power management devices including the present device; a signal collection part which, when it is recognized by the attribute recognition part that the attribute of the own device is the master device, collects control signals for controlling the electronic apparatus from (N-1) slave devices; and a signal selection part which selects the largest number of same kind control signals to transmit to the electronic apparatus, in the control signals collected by the signal collection part.
