To provide a relay device which can operate even when a contact is frozen, and to provide a vehicle power supply device which enables reduction of malfunctions during a cold period.SOLUTION: A relay device (33) includes: a first contact (A331) and a second contact (A332); a driving mechanism (334) which moves the first contact (A331) and the second contact (A332) close to or away from each other; a first conductor (331) electrically connected to the first contact (A331); a second conductor (332) electrically connected to the second contact (A332); and a static relay (336) and an electric heating element (337) connected between the first conductor (331) and the second conductor (332). The electric heating element (337) is disposed so as to be able to heat at least one of the first contact (A331) and the second contact (A332).SELECTED DRAWING: Figure 2

    【課題】接点に凍結が生じた場合でも動作可能なリレー装置、並びに、寒冷時において動作不良を低減できる車両の電源装置を提供する。【解決手段】リレー装置(33)は、第1接点(A331)及び第2接点(A332)と、第1接点(A331)と第2接点(A332)とを近接又は離間させる駆動機構(334)と、第1接点(A331)に電気的に接続された第1導体(331)と、第2接点(A332)に電気的に接続された第2導体(332)と、第1導体(331)と第2導体(332)との間に接続された無接点リレー(336)及び電熱体(337)とを備える。そして、電熱体(337)が、第1接点(A331)及び第2接点(A332)の少なくとも一方を加熱可能に配置されている【選択図】図2
