ELECTRICAL CONNECTION BOX

摘要

An electrical connection box (1) is provided with a circuit structure (10), and a casing (20) for storing the circuit structure (10) in the interior. The casing (20) is provided with: a case (30) on which an opening that opens to the side is formed, and which has a case side peripheral wall (32) installed so as to rise from the periphery of a bottom plate (31), and stores the circuit structure (10) in the interior; and a cover (50) which blocks the opening of the case (30) and which has a cover side peripheral wall (52) installed so as to rise from the peripheral edge of a lid plate (51) and for covering the periphery of the case side peripheral wall (32). The protruding edge of the cover side peripheral wall (52) extends to a position that approximately matches at least the outer surface of the bottom plate (31) when the cover (50) is attached to the case (30).
