PROBLEM TO BE SOLVED: To provide a power supply controller rarely generating connection failure.SOLUTION: The power supply controller includes: a power reception conductor 21 which is electrically connected to an external power source; a power supply conductor 22 which is electrically connected to an external charge circuit; a relay 11 that turns ON/OFF the electrical connection between the power reception conductor 21 and the power supply conductor 22; a control circuit 12 that controls the relay 11; and a power circuit 13 that receives the power from the external power source via the power reception conductor 21 to generate the power to the control circuit 12. The control circuit 12 and the power circuit 13 are mounted on a common printed wiring board 50. Comparing to the case where the control circuit 12 and the power circuit 13 are mounted on different printed wiring boards respectively, since the number of connection points is reduced by eliminating a conductor for connecting two printed wiring boards to each other, connection failure is relatively reduced. |
