A junction box cooling device in an automobile is provided to prevent components in a junction box from being damaged due to heat by attaching radiation bars to a bolt fastening a connector to a bus-bar layer and by attaching radiation plates to the radiation bar. A junction box cooling device in an automobile comprises radiation bars and a plurality of radiation plates. One end of the radiation bar is fastened to a bolt which couples a connector(13) of the junction to a bus-bar layer(14). The other end of the radiation bar protrudes out of the junction box. The radiation plates are circumferentially attached to the radiation bar. The connector is fit to a support protrusion(12) formed at a bottom cover(11) of the junction box. The radiation bar is inserted in the support protrusion to be coupled to the bolt.
