PROBLEM TO BE SOLVED: To provide an electric connection box with a novel structure, which can prevent a vehicle fire after immersed in water without depending on a waterproof structure of the electric connection box. ! SOLUTION: In an electric connection box 10 in which a power supply side bus bar 46b connected to a power supply line, and a plurality of bus bars 46a1, 46a2, 46b, 46c containing downstream side bas bars 46a1, 46a2 connected to an electrical load or a ground line, form an internal circuit, the power supply side bus bar 46b and downstream side bus bars 46a1, 46a2 are arranged adjacent to each other, while at least the power supply side bus bar 46b is formed of a clad steel obtained by bonding a copper material layer 50 and an aluminium material layer 52, and a surface 54 opposed to downstream side bus bars 46a1, 46a2 of the power supply bus bar 46b, is formed of the aluminium material layer 52. !
