Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a vehicular power supply apparatus that can output information on remaining life calculated in view of actual operational states of components on the basis of temperature information about the components.SOLUTION: A vehicular power supply apparatus 10 includes: components whose life is affected by temperature conditions; sensors 8, 8C for detecting temperature information about the components; and a control section 4. The control section 4 can calculate an integral value of temperature information over an actual operating time for the components, can hold or acquire estimated remaining life information estimating a change in remaining life with the integral value for the components, calculates a remaining life of the components through the integral value according to the estimated remaining life information, and outputs the calculated remaining life information.
