<p>PROBLEM TO BE SOLVED: To provide a junction box provided with a large current processing circuit section and a small level current processing circuit section which can realize reduction in size and cost down, while maintaining simplification of wiring and monitoring of current at bus bar wiring section. SOLUTION: A junction block 21 is structured by a large current processing circuit section 22 including a bus bar wiring section 34 having a power connectors 32a to 32d, a plurality of bus bars 33 and a fuse 26 provided via the bus bar 33, connectors 38a to 38c for signal, an arithmetic processing section 58, a branching and connection section 66 for branching and connecting the arithmetic processing section 58 and the connectors 38a to 38c for signal; and a low level current processing section 23 including a current detecting section 59 which is connected to the predetermined bus bars 33a, 33b of the bus bar wiring section 34 to detect change of current. Moreover, a current detecting resistor 57 is provided between the predetermined bus bars 33a, 33b of the heavier current processing circuit section 22 and the predetermined bus bars 33a, 33b of the heavier current processing circuit section 22, at the area near the part connected to the current detecting section 59 of the small level current processing circuit section.</p> |
