PROBLEM TO BE SOLVED: To provide circuit wiring construction in a junction block, capable of performing high-density wiring with various kinds of electric components, etc., arranged inside, and capable of contributing to cost reduction and enhancement of maintainability. SOLUTION: This circuit wiring construction in a junction block 21, in which a high-voltage system circuit and a low-voltage system circuit exist along with a plurality of electric components, etc. For the high-voltage system circuit, construction of performing wiring with bus-bars 22, 23 and a group of electric wires 24 is adopted. For the low-voltage system circuit, construction of performing wiring with a set of electric wires 25 is adopted. Also, wiring is performed using the bus-bars 22, 23 for a circuit in which a large current flows, and a group of electric wires 24 are used for a circuit in which a medium current flows, in the high-voltage system circuit.
