The drain outlet 12 is closed with a water infiltration preventive member 20 to absorb waterdrops infiltrating from the outside into the inside of the junction box main part 10 by the moisture penetration preventive member 20. The water infiltration preventive member 20 may be a sheet-type member 21 fixed to the circumference of the drain outlet 12.
