PROBLEM TO BE SOLVED: To improve conduction reliability of a junction box constituted by stacking a plurality of plates where conductive patterns are formed.SOLUTION: The junction box 10 includes an electric circuit constituted by laminating the plurality of resinous plates 51 having the conductive patterns 52 formed respectively and interconnecting desired conductive patterns by terminals penetrating the plates of respective layers. On a bottom (lower casing 60) of the junction box, a plurality of pole structures 61 which penetrate the respective plates of the respective layers are uprightly formed to be located at positions not overlapping the respective conductive patterns 52 of the respective layers. Insertion holes 53 are formed in the resinous plates 51 to allow the pole structures 61 to be inserted therethrough. The plurality of pole structures 61 are formed to have different heights. The insertion holes 53 are formed in each of the resinous plates 51 so as to allow the pole structures 61 to be inserted therethrough and to match the heights of the pole structures 61 having different heights. |
