PROBLEM TO BE SOLVED: To charge a battery with a different capacity with optimal current by a charger with a simple circuit structure. SOLUTION: The charger includes a first resistor 2A and a second resistor 2B connected in series and connected in series with a first battery 1A, and a charging power source 5 in which its charging current is controlled by a current controller 7 so that the voltage induced at both ends of the first resistor 2A and the second resistor 2B becomes constant. The charging power source 5 has the first output terminal 3A connected to the first resistor 2A, and the second output terminal 3B connected to the second electrode terminal 4B for connecting the battery 1. The first electrode terminal 4A for connecting the second battery 1B is connected to the connecting point 11 of the first resistor 2A to the second resistor 2B. The charger controls the charging power source 5 so that the added voltage of the voltages induced at the first resistor 2A and the second resistor 2B in the state that the first battery 1A is charged and the voltage induced in the first resistor 2A in the state that the second battery 1B is charged, become constant, and controls the charging current of the first battery 1A and the charging current of the second battery 1B.
