The present invention is to provide an electric connection box which can prevent a fuse attaching portion from being heated to high temperature. The electric connection box includes a fuse attaching portion in which a plurality of fuses are directly aligned and attached, a case body having a plurality of the fuse attaching portions on an upper surface thereof, and a hole provided between the fuse attaching portions, the hole passing through the case body from a lower surface to the upper surface thereof. The hole is separated into a small hole smaller than a size of the fuse by a partition wall.
