PROBLEM TO BE SOLVED: To improve waterproof performance, keep manufacturing cost, and prevent an electrical junction box from being accumulated with heat and increase in inner temperature, while the inner part as a whole is cooled surely. SOLUTION: In an electrical junction box 1, a plurality of electric heating parts 5 are included in a main junction box body 2, and an upper box-shaped cover 2 and a lower box-shaped cover 4 are assembled. At least a thermoelectric cooling element 6 is provided in the vicinity of the electric heating part 5 to absorb heat from the electric heating part 5 at continuity time, and at the same time the electric junction box is prevented from being accumulated with heat. The heat-absorbing face of the thermoelectric cooling element 6 is put on a side near the electric heating part 5. Element holders 22 and 27 for mounting each thermoelectric cooling element 6 are extended from each inner face of the upper and lower covers 3 and 4 toward the electric heating part 5. The element holders 22 and 27 are extended from each face of the upper or lower cover 3 or 4 and the main junction box body 2 toward the electric heating part 5. The element holders 22 and 27 are extended from each face of the upper and lower covers 3 and 4 and the main junction box body 2 toward the electric heating part 5. In this case, the upper or lower cover 3 or 4 is formed integrally the main junction box body. |
