PROBLEM TO BE SOLVED: To improve heat radiation performance of an electric connection box.SOLUTION: An electric connection box 10 includes: a first circuit part 21 on which a first heating component 11 is mounted; a second circuit part 22 in which a second heating component 12 is mounted; a first heat radiation member 31 which is overlapped with the first circuit part 21 and radiates heat of the first circuit part 21; a second heat radiation member 32 which is overlapped with the second circuit part 22 and radiates heat of the second circuit part 22; and a metal support member 40 disposed between the first heat radiation member 31 and the second heat radiation member 32 and supporting the first heat radiation member 31 and the second heat radiation member 32. The support member 40 has a heat reception part 41 which is disposed between the first circuit part 21 and the second circuit part 22 and receives heat of the first heating component 11 and the second heating component 12.SELECTED DRAWING: Figure 2 【課題】電気接続箱の放熱性を向上させる。【解決手段】電気接続箱１０は、第１発熱部品１１が実装される第１回路部２１と、第２発熱部品１２が実装される第２回路部２２と、第１回路部２１に重ねられ、第１回路部２１の熱を放熱する第１放熱部材３１と、第２回路部２２に重ねられ、第２回路部２２の熱を放熱する第２放熱部材３２と、第１放熱部材３１と第２放熱部材３２との間に配されて第１放熱部材３１及び第２放熱部材３２を支持する金属製の支持部材４０と、を備え、支持部材４０は、第１回路部２１と第２回路部２２との間に配されて第１発熱部品１１及び第２発熱部品１２の熱を受ける熱受け部４１を有する。【選択図】図２
