Abstract
To provide an electrical junction box that enables simple and low-cost power distribution between multiple blocks within the electrical junction box. [Solution] The electrical junction box 1 comprises a first block 10 and a second block 20, each having a separate shape independent of the others and assembled to one another. The first block 10 includes a first housing 11 in which electronic components are stored, and a first busbar 12 held in the first housing 11. The second block 20 includes a second housing 21 assembled to the first housing 11, and a second busbar 22 held in the second housing 21 and having an extension portion 25 that overlaps with and electrically connects to the first busbar 12. The first busbar 12 and the second busbar 22 are arranged so that the through holes 19 and 26 in the extension portions 25 of the first busbar 12 and the second busbar 22 are in communication with each other, and the electrically connected state is maintained by fasteners 30 inserted into the through holes 19 and 26.
