A hybrid power supply device is provided with a fuel cell, an electric storage device that is connected in parallel to the fuel cell via a switch, and a control circuit that controls connection between output terminals of the fuel cell and the electric storage device by controlling on/off of the switch. Here, the control circuit controls the connection between the output terminals based on an output current of the fuel cell, and disconnects the output terminals when the output current of the fuel cell becomes equal to or smaller than a predetermined lower limit current while the output terminals are connected.
