For providing an electric connection box including a metal core board, which can limit increase of a size thereof and be prevented from bending along the slit, the electric connection box 10 includes a metal core board 1, in which a plurality of core metal plates 21, 22 is laminated and insulation resin is filled between each of the plurality of core metal plates 21, 22. The plurality of core metal plates 21, 22 are provide with slits 3A, 3B to divide the core metal plates 21, 22 to a plurality of separate plates 21a, 21b, 22a, 22b and be filled with insulation resin. The slits 3A, 3B is formed not to overlap each other on the same one line when viewing in a vertical direction about the metal core board 1. The electric connection box 10 distributes electric power inputted from a plurality of power systems to each separate plates 21a, 21b, 22a, 22b. |

1. A metal core board which is used for an electric connection box, comprising:
a plurality of core metal plates to be laminated that are separated in a vertical direction; insulation resin filled between each of the plurality of core metal plates; and a slit formed in at least one of the plurality of core metal plates so as to divide the core metal plate to a plurality of separate plates and being filled with the insulation resin therebetween, wherein the slit is disposed to entirely overlap, at a corresponding lateral position, a region of another vertically separated core metal plate that defines a contiguous sheet of metal so that each contiguous sheet of metal at the corresponding lateral position overlaps at least one slit, and wherein the slit is not formed in at least one of the plurality of core metal plates, thereby a part of the core metal plate having a weak strength due to formation of the slit is reinforced. |
