PROBLEM TO BE SOLVED: To provide an electrical junction box with a vertical difference in the level of an edge of a frame which can prevent water intrusion into the frame from a region of mating of the frame and a cover, without using packing.SOLUTION: An electrical junction box 1 includes a frame 2 and a cover 3 covering an opening 20 of the frame 2. An edge 21a of a peripheral wall 21 of the frame 2 has a level difference, and the edge 21a has a low region 4, a high region 6 and a slant region 5. The cover 3 is provided with a double wall 33 comprising an outer wall 31 and an inner wall 32 and positioning the edge 21a of the peripheral wall 21 between the outer wall 31 and the inner wall 32. An edge 32a of the inner wall 32 has a level difference like the frame 2, and the edge 32a has a low region 14, a high region 16 and a slant region 15. A lap between the peripheral wall 21 and the inner wall 32 in the slant regions 5, 15 is formed larger than a lap in the low regions 4, 14. |
