In a circuit module having components that are fastened to a substrate, the substrate includes a carrier layer made of metal and having a first surface, a first insulating layer bordering directly on the carrier layer being situated on the first surface. The substrate also includes a first wiring layer bordering directly on the first insulating layer, which conducts electrically and is situated on the first insulating layer. The substrate includes a first contact plane, which runs along the first surface, at least one of the components being directly connected electrically to the carrier layer in the first contact plane.
