An electric component has a housing part and a component support which is provided with a conductor path structure. The conductor path structure has an interruption, by which a connection section of the conductor path structure is galvanically separated from a main section of the conductor path structure. The component support is arranged on the housing part such that a heat-conductive connection is produced between the component support and the housing part. The main section remains galvanically separated from the housing part. The electric resistance between the main section of the conductor path structure and the housing part is measured. The component support is secured to the housing part by a securing element. The interruption is electrically bridged by the securing element and the main section is electrically conductively connected to the housing component.
