To provide a high-voltage electrical junction box that can prevent an occurrence of a leakage current and improve reliability of connection, that can reduce cost by achieving an easy assembly operation, and further make an effective use of an in-vehicle space by realizing miniaturization. A high-voltage electrical junction box 1 includes an insulating box body 13 and a circuit structure 14 accommodated in the box body 13. The circuit structure 14 includes a group of bus bars 22 of a high-voltage system disposed on an upper surface 21a of the board 21, a group of printed patterns 41 of a low-voltage system formed on a lower surface 21b of the board 21, a through hole 23 formed to penetrate through each bus bar, the board 21 and each printed pattern, and a connecting piece 24 that is inserted into the through hole and connected to each bus bar, the board 21 and each printed pattern. |
