1. A semiconductor module comprising a conducting member, wherein the conducting member electrically connects a semiconductor element arranged on a substrate or a bus bar with another electronic component and is provided with a structure having flexibility capable of, in a junction with the semiconductor element, reducing thermal stress due to difference in a coefficient of linear expansion between the conducting member and the semiconductor element, and absorbing dimensional error in objects to be connected,
wherein the semiconductor module further comprises a cooling surface structural part which is insulated from the semiconductor element and is installed on the substrate or the bus bar; and
wherein the conducting member is electrically connected to the semiconductor element and the other electronic component via the cooling surface structural part.
