ABSTRACT:
A bus bar structure which can detect current exceeding the rated allowance of the current sensor and which does not involve insertion of the bus bar, thereby increasing the current sensor detection range, reducing the cost of manufacture due to downsizing of the magnetic core, improving the degree of freedom in the arrangement of the bus bar, and improving the operability of assembling the current sensor to the bus bar. The bus bar structure includes: an electrical junction box (21) to be mounted on a motor vehicle; a bus bar (37) arranged on the electrical junction box (21), the bus bar (37) serving as a bus bar from which to detect current; a current sensor (23) that is mounted on the electrical junction box (21); and a shunt bus bar (31) that is integrally formed with the current sensor (23) while passing through a magnetic core of the current sensor (23). In such a bus bar structure, both ends of the shunt bus bar (31) projecting from the current sensor 23 are connected in parallel to the current detection bus bar (37).
