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.
