An electric junction box, disposed in a water penetration region, which accommodates bus bars inside a case body thereof and has fuses (fusible links connected with the bus bars. An upper cover and a lower cover are mounted on the case body with the case body, the upper cover, and the lower cover connected with one another. An entire peripheral wall of the upper cover is formed not as a double-wall construction, but an inner peripheral surface of the peripheral wall is brought into contact with an outer surface of an entire peripheral wall of the lower cover (or case body) to lock the peripheral wall and the entire peripheral wall of the lower cove to each other. In a watertight region including at least the fuses, a rib is projected in the shape of a frame from an inner surface of an upper wall of the upper cover so that the rib surrounds the watertight region.
