To provide a relay abnormality determination device and a system capable of determining abnormality on multiple relays that are connected in series with a drive unit that turns on and off the multiple relays, and which are connected to each other in parallel.SOLUTION: A first relay 31 and a second relay 32 are connected to each other and are connected to a drive unit 40 in series. A relay abnormality determination device 60 in a relay abnormality determination system 1 is configured to determine an abnormality on the first relay 31 and the second relay 32 on the basis of decrease in a current flowing through the drive unit 40 via the first relay 31 and the second relay 32 when the first relay 31 and the second relay 32 are normal.SELECTED DRAWING: Figure 1 【課題】複数のリレーをオンオフさせる駆動部と直列に接続されているとともに互いに並列に接続された複数のリレーの異常を判定するリレー異常判定装置およびリレー異常判定システムを提供する。【解決手段】第１リレー３１および第２リレー３２は、互いに並列接続されているとともに駆動部４０と直列に接続されており、リレー異常判定システム１のリレー異常判定装置６０は、第１リレー３１および第２リレー３２が正常であるときの第１リレー３１および第２リレー３２を介して駆動部４０に流れる電流からの低下に基づいて、第１リレー３１および第２リレー３２の異常を判定する。【選択図】図１
