PROBLEM TO BE SOLVED: To provide an electronic control device that is able to acquire air permeability and waterproofness for the interior of a housing by restricting protrusion of the housing toward the outer peripheral side.SOLUTION: A circuit board 4 on which an electronic component is mounted is accommodated in the internal space of a housing 1 formed by joining a plurality of housing members such as a case 2, a cover 3, etc. A ventilation passage 50 is formed in the housing member 3. The ventilation passage comprises: a thickness-part through-hole 5 having external-wall openings 36a, 36b located with a distance between them in the peripheral edges of the external walls of thick parts as of corner parts 30 or angular parts 35 and formed through a space between the external wall openings 36a, 36b; a communication hole 6 communicating with the internal wall 37 of the thick part and the through-hole 5 of the thick part; and an air permeable waterproof film 7 mounted in the inside opening 6a of the communication hole 6 on the inside of the housing 1.SELECTED DRAWING: Figure 1

    【課題】筐体において外周側への張り出しを抑制し、筐体内部の通気性および防水性を得ることが可能な電子制御装置を提供する。【解決手段】ケース2やカバー3等の複数の筐体部材を接合して成る筐体1の内部空間に、電子部品を実装した回路基板4を収容する。筐体部材3に、コーナー部30や角部35等の肉厚部における外壁面の周縁側にそれぞれ互いに距離を隔てて位置する外壁面開口部36a,36bを有し当該各外壁面開口部36a,36bの間を貫通して形成された肉厚部貫通孔5と、肉厚部の内壁面37と肉厚部貫通孔5との間を連通する連通孔6と、連通孔6の筐体1内部側の内側開口部6aに取り付けられた通気性および防水性の通気防水膜7と、を備えた通気通路50を形成する。【選択図】図1
