This vehicular charging device is provided with a contactless power-receiving unit (3) that contactlessly receives high-frequency AC power, a wired power-receiving unit (2) that is connected to a low-frequency AC external power supply (21), a rectifier (5) that rectifies the AC power, a subsequent power converter (6), and a power-receiving-unit switching means (4) that switches between power being outputted from the contactless power-receiving unit (3) to the rectifier (5) and power being outputted from the wired power-receiving unit (2) to the rectifier (5). A high-frequency removal means (7) that removes high-frequency components is provided between the rectifier (5) and the power converter (6). When receiving power from the contactless power-receiving unit (3), the power converter (6) performs a resistive transforming operation in which the voltage inputted to the power converter (6) is raised or lowered and a constant voltage is outputted, and when receiving power from the wired power-receiving unit (2), the power converter (6) performs a power-factor correction operation in which the power factor of the power inputted from the external power supply (21) is corrected and a constant voltage is outputted.
