摘要： An object of the present invention is to reduce electric power consumption of a charger as much as possible when charging is not performed, and also to improve operation performance of the charger.
A charger (10) according to the present invention includes a charging power source circuit for charging a battery, a power source control circuit that controls the charging power source circuit, a microcomputer (28) that operates the power source control circuit, and a constant voltage power source circuit (50) that supplies electric power to both the power source control circuit and the microcomputer (28). The microcomputer (28) is configured to permit or prohibit supply of electric power to the power source control circuit from the constant voltage power source circuit (50) to the power source control circuit.
