PROBLEM TO BE SOLVED: To improve cooling performance of an electronic component.SOLUTION: An electric connection box comprises a housing 10 having: a main body component 11 which is provided with a second housing chamber 22 for a second electronic component 102 acting as a heat generation source; a cover component 12 closing an opening 11a on one end of the main body component; and a wire lead-out part 41 for leading a wire 150 to the outside. The second housing chamber 22 has first and second walls 22a and 22b which face each other and also face two wide-area portions 102a of the second electronic component, respectively. The first wall 22a has an air inlet port 61 which is formed on one end side in the perpendicular direction to an insertion direction of the second electronic component so as to draw fresh air into the second housing chamber. The second wall 22b has an air outlet port 62 which is formed on the other end side in the perpendicular direction so as to discharge air inside the second housing chamber to the outside of the second housing chamber. The housing has: a fresh air introduction port 63 which is arranged closer to the air outlet port side than the air inlet port in the perpendicular direction so as to introduce the fresh air from the outside of the housing; and a fresh air passage 64 for guiding the fresh air from the fresh air introduction port to the air inlet port.SELECTED DRAWING: Figure 7

    【課題】電子部品の冷却性能を向上させること。【解決手段】発熱源となる第2電子部品102の第2収容室22が形成された主体部品11と、主体部品の一端の開口11aを塞ぐカバー部品12と、電線150を外部に引き出す電線導出部41と、を有する筐体10を備え、第2収容室22は、互いに対向すると共に第2電子部品の2箇所の広域部102aに対しても各々対向する第1及び第2の壁部22a,22bを有し、第1壁部22aは、第2電子部品の挿入方向に対する直交方向の一端側に形成され、第2収容室の内部に新気を流入させる吸気口61を有し、第2壁部22bは、直交方向の他端側に形成され、第2収容室の内部の空気を当該第2収容室の外部に排出する排気口62を有し、筐体は、直交方向にて吸気口よりも排気口側に配置され、筐体の外部から新気を導入する新気導入口63と、新気導入口から吸気口に新気を案内する新気流路64と、を有すること。【選択図】図7
