ELECTRICAL CONNECTION BOX

摘要

An object of the present invention is to provide an electrical connection box in which reduction in weight can be achieved by simplification of the construction, while preventing short-circuiting of a positive electrode side busbar and a negative electrode side busbar. An electrical connection box (1) includes: a positive electrode side busbar (2A) connected to a positive electrode of a battery; a negative electrode side busbar (2B) connected to a negative electrode of the battery; and a case (3) in which the positive electrode side busbar and the negative electrode side busbar are accommodated. The case includes: a bottom wall (4); a circumferential wall (5) erected from the bottom wall; and a partition wall (6) erected from the bottom wall. The partition wall is a waterproof partition that partitions a positive electrode side busbar accommodating area (41) in which the positive electrode side busbar is accommodated and a negative electrode side busbar accommodating area (42) in which the negative electrode side busbar is accommodated.
