PROBLEM TO BE SOLVED: To provide an electronic device for an automobile having high reliability at a low cost. SOLUTION: The electronic device for an automobile comprises housings 11, 12 each having a first storage space, and an electronic unit having a board 21, an element 22 mounted on the board 21, a silicon heat sink 31, and a connector 211 so that the heat sink 31 is spaced from the connector 2. The heat sink material is interposed between an element used for the electronic unit and a heat sink to improve adhesive properties between the element and the heat sink by the magnitude of the heat resistance of the material. However, a low molecular weight siloxane compound is volatilized by heating from the heat sink material, an oxide film is formed on a terminal such as the connector to bring about a contact fault between the terminals. The siloxane compound volatilized from the material prevents an influence from directly affecting the connector by being spaced between the material and the connector. COPYRIGHT: (C)2003,JPO
