PURPOSE: An apparatus for cutting off electric power at collision is provided to prevent a fire of a vehicle due to a short circuit phenomenon and a spark by cutting off the electric power applied to wires of the vehicle at collision. CONSTITUTION: An adhesive bottom plate(1) is adhered to a vehicle. An input copper terminal(7) having a fuse ball loading contact portion(9) and an output copper terminal(8) are fixed at the adhesive bottom plate(1) by using a plurality of terminal fixing bolts(7b,8b). A support cover(2) is adhered on the adhesive bottom plate(1). A heavy fuse ball(6) is located between a fuse ball pushing portion(5) as an insulator and the fuse ball loading contact portion(9) in a normal state. The heavy fuse ball(6) is ejected at collision and the fuse ball pushing portion(5) is contacted with the fuse ball loading contact portion(9).
