A waterproof cover ( 13 ) is provided on an upper surface ( 11 b ) of a casing( 11 ) of an electrical connection box ( 10 ). The waterproof cover ( 13 ) is formed with a recess ( 13 b ) for collecting water fallen down on the outer surface of the waterproof cover ( 13 ). One end of the recess ( 13 b ) with respect to a longitudinal direction is raised to form a water-diverting portion ( 13 d ), a rib ( 13 c ) projects up at the other end of the recess ( 13 b ), and a dropping portion ( 13 e ) is provided below the rib ( 13 c ). Waterdrops M that fall down on the outer surface of the waterproof cover ( 13 ) stay temporally in the recess ( 13 b ) and drain along the dropping portion ( 13 e ) when the water level thereof exceeds the rib ( 13 c ). Further, a slanted guide ( 12 c ) projects from a bracket ( 12 ) below the dropping portion ( 13 e ).
