The junction box comprises an insulated housing, the conductive terminals and the water-resistant members. The bottom of the junction box disposes the first openings. The water-resistant members disposed at the first openings have second openings whose areas are smaller than those of the first opening. The base plate disposes the third openings whose areas are smaller than those of the first opening. The third openings are assembled with the first openings and the second openings. Pairs of wing portions provided with a first preset distance, which is shorter than the width of the junction box, are aligned at both lateral sides of the base plate. The average width of the base plate is not greater than 50 millimeter.
