The invention provides an in-vehicle communication device and an in-vehicle communication system, which can be expected to reduce the number of parts where connectors of communication lines are directly connected with each other in a vehicle. An in-vehicle communication device according to the present embodiment is provided with: a first connection unit, a second connection unit, and a third connection unit that are each connected to a communication line provided in a vehicle; a communication unit that performs communication via a communication line; a first communication path disposed between the first connection unit and the communication unit; a second communication path that directly connects the second connection unit and the third connection unit; and a switching unit that switches between the first communication path and the second communication path to a connection state or a disconnection state.

    本发明提供一种车载通信装置及车载通信系统,能够期待减少在车辆中通信线的连接器彼此直接连接的部位的数量。本实施方式所涉及的车载通信装置具备:第一连接部、第二连接部和第三连接部,分别与设置在车辆内的通信线连接;通信部,经由通信线进行通信;第一通信路径,配置在所述第一连接部与所述通信部之间;第二通信路径,将所述第二连接部与所述第三连接部之间直接连结;及切换部,将所述第一通信路径与所述第二通信路径之间切换为连接状态或切断状态。
