ELECTRICAL CONNECTION BOX

摘要

An electrical connection box (1) is provided with: a case (30) having a bottom plate (31), a case side peripheral wall (32) installed so as to rise from the peripheral edge of the bottom plate (31), and an opening (41) opening to the side; a circuit structure (10) stored in the interior of the case (30); and a cover (50) which blocks the opening (41) of the case (30) and has a lid plate (51), and a cover side peripheral wall (52) installed so as to rise from the peripheral edge of the lid plate (51) and for covering the periphery of the case side peripheral wall (32). The circuit structure (10) is provided with a circuit substrate (11), and an electronic component (12) mounted on the mounting surface (17) of the circuit substrate (11), wherein the circuit substrate (11) is stored in the interior of the case (30) such that the mounting surface (17) faces the opening (41). The circuit structure (10) is disposed in the interior of the case (30) in a manner such that a space, through which water passes, is formed between the circuit structure (10) and the inner surface of the bottom plate (31).
