A vehicular power supply device is provided with: a plug socket (22) for supplying electric power to an external device; and an external output switch (33) that switches between an on-state in which the electric power is supplied from the battery (11) to the plug socket (22) and an off-state in which the electric power supply is stopped. When the vehicle transitions from a ready mode to an OFF mode with the external output switch (33) in the on-state, the external output switch (33) is placed in the off-state in accordance with the transition. When the vehicle transitions from an ACC mode or an ON mode to the OFF mode, the external output switch (33) is maintained in the on-state. |
