Abstract
In an electric connection box, a heat insulation wall is vertically extended in a case. This forms, between the heat insulation wall and the inner wall of the case, an ascending flow path where air can ascend and a descending flow path where air can descend. An upper communication opening and a lower communication opening that connect between the ascending flow path and the descending flow path are arranged at the upper end and the lower end, respectively, of the heat insulation wall. A relay is placed in the ascending flow path. Among the regions of the case, a region forming the descending flow path is provided with a heat radiation wall section for releasing heat of air in the descending flow path to the outside of the case.
