ABSTRACT:
The invention is designed to improve a radiation effect of a junction box so as to eliminate a limit in a current to be applied to busbars. A filler 15 of epoxy resin is injected into the interior of coupled lower and upper casings 1 and 3 through injection holes formed in suitable positions of the casings 1 and 3 so as to fill the interior with the filler 15. Since air layers within the coupled casings 1 and 3 can be eliminated by the filler 15, heat generated due to application of a current to busbars 11 can be efficiently radiated via the filler 15 and the casings 1 and 3, thereby improving a radiation effect within the junction box. Therefore, it is not necessary to limit a current applied to the busbars, and a relatively large current can be applied to the busbars.
