An electric junction box is disposed in a water penetration region and accommodates bus bars and fuses connected with the bus bars inside a case body. The case body is connected with an upper cover and a lower cover, with the upper cover and the lower cover mounted on the case body. An entire peripheral wall of the upper cover is formed not as a double wall, but the entire peripheral wall of the upper cover is locked to a peripheral wall of the lower cover (or case body), with an inner peripheral surface of the peripheral wall in contact with an outer surface of an entire peripheral wall of the lower cover (or case body). In a watertight region including at least the fuses, a rib is projected in a shape of a frame from an inner surface of the upper wall of the upper cover to surround the watertight region.
