PROBLEM TO BE SOLVED: To provide an electrical junction box for radiating heat from the inside of the electrical junction box effectively to the outside thereof through a terminal holding spacer. SOLUTION: In an electrical junction box 100, a terminal holding spacer 20 passed into a main box body 10 of the electrical junction box 100 for preventing a connection terminal 4 from coming off has a radiating fin 25. The radiating fin 25 is exposed outside the main box body 10 for removing heat from the in side of the main box body 10. After the heat of a fuse (F) generated by the flowing current is received by each fitting parts 21, 22 and 23 of the terminal holding spacer 20, the heat is radiated via a connection part 24 and the radiating fin 25 to the outside of the main box body 10. Then, the increase in temperature inside the electrical junction box 100 can be surely prevented, and deterioration due to heat of the electrical junction box 100 and the fuse (F) can be reduced. |
