The purpose of the present invention is to provide an electronic component unit and a wire harness capable of appropriately supplying power to various devices mounted on a vehicle. An electronic component unit (10) applied to a wire harness is provided with: a power supply terminal (11) connected to a power supply (B2) mounted on a vehicle and capable of supplying power at a first voltage (V1); a circuit branching unit (13) that is connected to the power supply terminal (11) and branches power supplied from the power supply (B2) to a plurality of power supply systems (PL); and a voltage converter (15) that is provided in at least one power supply system (PL) among the plurality of power supply systems (PL) in the circuit branching unit (13), converts the voltage of the power supplied from the power supply (B2) to a second voltage (V2) that is lower than the first voltage (V1), and outputs the second voltage (V2).

    本发明的目的在于提供一种能够对搭载于车辆的各种设备适当地供给电力的电子部件单元以及线束。应用于线束的电子部件单元(10)具备:电源端子(11),其与电源(B2)连接,电源(B2)搭载于车辆且能够以第一电压(V1)供给电力;电路分支部(13),其与电源端子(11)连接,使从电源(B2)供给的电力分支至多个电源系统(PL);以及电压转换器(15),其在电路分支部(13)中设置于多个电源系统(PL)中的至少一个电源系统(PL),将从电源(B2)供给的电力的电压转换为比第一电压(V1)低的第二电压(V2)并输出。
