Abstract: An electrical junction box has fuse attachment portions arranged side by side and open to a lateral side of a box body. Recesses (88) are formed at opposite side edges of an L-shaped bend (78) of each of connecting terminals (48a-48c), and in a terminal support block (42) in which a plurality of terminal insertion holes (54a) to (54c) are formed and support pins (74) that lock the connecting terminals (48a) to (48c) are inserted, temporal retaining portions (68) are formed in respective opening ends (70) of the terminal insertion holes (54a-54c) on a terminal insertion side, the temporal retaining portions (68) temporarily positioning the connecting terminals (48a) to (48c) within the respective terminal insertion holes (54a-54c) by the recesses (88) of the connecting terminals (48a) to (48c) being fit into the temporal retaining portions (68).
