A vehicle electricity storage device includes a capacitor unit for supplying stored electric power to an electronically controlled system, and a microcomputer including a memory. The memory stores a plurality of thresholds (internal resistance limit values) different from each other. Each of the plurality of thresholds is to be compared with an electrical characteristic value (internal resistance value) related to the capacitor unit for determining a deterioration state of the capacitor unit. The each of the plurality of thresholds is stored in association with an identification ID for identifying the electronically controlled system. The microcomputer acquires the identification ID from the electronically controlled system. And the microcomputer selects, from the plurality of thresholds, a threshold associated with the identification ID acquired. Then the microcomputer determines the deterioration state of the capacitor unit by using the electrical characteristic value and the threshold selected.
