ELECTRIC CONNECTION BOX

PROBLEM TO BE SOLVED: To provide an electric connection box which is excellent in decommisioning operation efficiency by providing it with a fragile part. SOLUTION: The electric connection box 10 is constituted such that a circuit structure 20 is stored in a casing 15 and further a fuse block 13 to accommodate a fuse and a connector 14 to perform connection between itself and the outside can be mounted. Moreover, the casing 15 is composed of a resinous frame 16 which surrounds the side of the circuit structure 20, a resinous cover 17 which surrounds the topside of the circuit structure 20, and a metallic heat radiating plate 30 which surrounds the bottom side (bus-bar side) of the circuit structure 20. A mount 32 with a bored through hole 33 is made integrally in the heat radiating plate 30, and also a notch 35 is formed at the margin of the through hole. At the decommisioning operation of a vehicle, by pulling a wire harness connected with the connector 14 strongly, the notch 35 is expanded and deformed, and a bolt B is detached from the point of the deformation and the electric connection box 10 is teared off.
