ELECTRONIC CONTROL UNIT

PROBLEM TO BE SOLVED: To prevent breakage of a jointing portion by reducing a stress generated at the joint portion between a plurality of lead portions and a substrate of a bus bar, when there is a temperature change. SOLUTION: A basket body, protruded and provided at a side wall around a plate portion in which the substrate of an electronic control unit, is fixed with a prescribed distance is fixed with an edge surface of the sidewall brought into contact with an upper surface of a housing in which a machine is provided. The fixing portion of the bus bar connected with the terminal guided out of the housing side is fixed at a substrate side attachment surface of a plate portion with a branch portion, in which a plurality of lead portions branch a free end. The respective top end portions of the plurality of lead portions are jointed with the substrate. A flexible portion for reducing the stress generated at the joint portion of the bus bar, when temperature changes is formed along the substrate side-attached surface, roughly in parallel.
