Electrically conductive adhesive sheet, method of manufacturing the same, and electric power conversion equipment

摘要

In order to solve the issue mentioned above, the present invention is featured in electrically conductive adhesive sheet: wherein the substrate 1 which composes electrically, thermally, or electrically and thermally conducting paths in a direction along the plane of the sheet is formed of metallic foil having a coefficient of thermal expansion between the coefficient of thermal expansion of one of at least two bonded members and the coefficient of thermal expansion of another one of the bonded members. In accordance with the present invention adopting the composition mentioned above, a stress applied to the protrusion layer 2, which composes electrically, thermally, or both electrically and thermally conducting paths between the substrate 1 and the bonded members by difference in thermal expansion, can be moderated.
