To make power supply from a battery to a power supply object difficult to stop.SOLUTION: A vehicular power supply device 10 includes: a first positive electrode side relay 51; a second positive electrode side relay 52; and a positive electrode side switch section 53. The first positive electrode side relay 51 is provided in a first positive electrode side branch passage 31 between a battery 20 and a first power supply object 21. The second positive electrode side relay 52 is provided in a second positive electrode side branch passage 32 between the battery 20 and a second power supply object 22. The positive electrode side switch section 53 is provided between a first positive electrode side conductive passage 33 to be a passage on the first power supply object 21 side of the first positive electrode side relay 51 in the first positive electrode side branch passage 31 and a second positive electrode side conductive passage 34 to be a passage on the second power supply object 22 side of the second positive electrode side relay 52 in the second positive electrode side branch passage 32.SELECTED DRAWING: Figure 1

    【課題】バッテリから電力供給対象への電力供給を途絶えにくくする。【解決手段】車両用電源装置10は、第1正極側リレー51と、第2正極側リレー52と、正極側スイッチ部53と、を備える。第1正極側リレー51は、バッテリ20と第1電力供給対象21の間において、第1正極側分岐路31に設けられる。第2正極側リレー52は、バッテリ20と第2電力供給対象22の間において、第2正極側分岐路32に設けられる。正極側スイッチ部53は、第1正極側分岐路31のうち第1正極側リレー51よりも第1電力供給対象21側の経路である第1正極側導電路33と、第2正極側分岐路32のうち第2正極側リレー52よりも第2電力供給対象22側の経路である第2正極側導電路34と、の間に設けられる。【選択図】図1
