The electrical junction box X includes an upper cover 1 , a distributing board 4 fitted with a busbar 5 , a wiring sheet 6 , and the lower cover 10 . The lower cover 10 is formed with a through-hole 8 a which is inserted by a terminal 5 ′ of the busbar 5 . The wiring sheet 6 is provided with a through-hole 7 a through which the terminal 5 ′ of the busbar 5 is inserted. This allows a smaller assembling tolerance between the terminal 5 ′ of the busbar 5 and the through-hole 8 a in combination of the wiring sheet 6 b attached to the distributing board 4 with the lower cover 10.
