A check valve is described for a gas-carrying line in a motor vehicle, in particular for the venting of a crankcase, having a valve housing which has a valve seat, a valve disk which abuts against the valve seat in a closed position and an electric heating device for heating the valve housing, wherein the valve disk is integrally configured with a spring and fastening section that is fixed to the valve housing and generates a closing force that presses the valve disk against the valve seat, and wherein the valve housing has a metal body, which forms the valve seat and on its outside forms a thermal coupling surface, on which the electric heating device sits and which extends together with the electric heating device beyond the valve seat both in the flow direction and in the opposite direction.
