There is provided a charging apparatus that enables safe and stable charging operation upon switching of power supplies for charging use. The charging apparatus has: first power supply 111 that has a current limiting function; second power supply 112 that has a current limiting function lower than the current limiting function of first power supply 111; first charging circuit 120 that charges battery 101 using first power supply 111; second charging circuit 130 that charges battery 101 using second power supply 112; and power supply selecting circuit 140 that detects the voltage of the first power supply and the voltage of the second power supply and controls charging operation of the second charging circuit based on the detected results. The charging apparatus selects one of first charging circuit 120 and second charging circuit 130 based on the output voltage of first power supply 111 that has a current limiting function, and controls the charging current upon charging operation from second power supply 112 that has a lower current limiting function.
