PROBLEM TO BE SOLVED: To provide an electric connection box including a bolt fixing portion capable of securing sufficient rigidity which withstands fastening torque of a mounting bolt while suppressing warpage.SOLUTION: A first fixture plate 42 and a second fixture plate 62 are respectively projected on peripheral walls 20 and 52 of a first case 12 and a second case 14. A first reinforcement rib 38 and a second reinforcement rib 70, which are respectively projected outward from the peripheral walls 20 and 52, are concatenated on both side edges of the fixture plates 42 and 62. Further, a peripheral rib 72 is formed on an outer periphery of the second fixture plate 62. The first fixture plate 42 and the first reinforcement rib 38 are respectively lapped with the second fixture plate 62 and the second reinforcement rib 70, and the first fixture plate 42 is fitted into the inner side of the peripheral rib 72 to form a bolt fixing portion 74 having an insertion hole 76 of a mounting bolt. |
