An electric connecting structure between a substrate and an electric component includes a substrate mounted in a case, an electric component assembled to a member which the case is mounted, a bus bar fixed to the case and connected to an electric circuit on the substrate at its one end and a spring disposed in compressed state between the bus bar and an electrode formed on the electric component. The substrate is electrical lyconnected to the electric component through the bus bar and the spring and a held portion formed on the spring is held by a spring holding portion integrally formed on the bus bar.
