PROBLEM TO BE SOLVED: To provide a power source controlling device for vehicle which prevents a dead battery from occurring while ensuring visibility right after the starting of traveling. SOLUTION: This power source controlling device for vehicle is used for loads excepting essential loads of a traveling system and a safety system. The power source controlling device is equipped with a current detecting means or a voltage detecting means, a controlling means, and a time measuring means. In this case, the current detecting means measures a current which flows from a battery to the load, and the voltage detecting means measures a voltage which is fed from the battery to the load. The controlling means performs a power feeding control which limits a power feeding to the load when the current value or the voltage value measured by the current detecting means or the voltage detecting means is lower than a specified threshold value. The time measuring means measures a period of time since an ignition key has been turned on. The controlling means sorts loads into a visibility ensuring load regarding the ensuring of visibility and general loads other than that. The controlling device for vehicle power source is constituted in such a manner that the power feeding is performed to the visibility ensuring load until a specified period of time of the time measured by the time measuring means has passed even when the current value or the voltage value detected by the current detecting means or the voltage detecting means is at the specified threshold value or lower.
