ABSTRACT:
To provide an electrical connection box which can easily respond to a change in the circuit construction among different types of vehicles and among different grades of the same type of vehicles, and can be generally used, an internal circuitry of an electrical connection box is divided into a common circuitry 1 and a special circuitry 2. A conductive layer on which the common circuitry 1 is formed and another conductive layer on which the special circuitry 2 is formed are arranged one over the other at different levels in a casing of the electrical connection box. The common circuitry 1 comprises flat busbars 10, whereas the special circuitry 2 preferably comprises a wire, longitudinal busbars 20, or a flat circuit 25 such as a flexible printed circuit (FPC) or a printed circuit board (PCB). The common circuitry 1 and the special circuitry 2 may alternatively be formed of the same conductive material.
