An electric vacuum pump, in particular for arrangement in a vehicle, having an electric motor and a pump part, which can be driven by the electric motor, so that air can be drawn into the pump part from a suction connection and wherein air can be taken out of the pump part out of an outlet connection. A motor flange is provided on which the pump part rests, and the outlet connection is disposed on the motor flange. A receiving space is formed in the motor flange into which space the outlet connection opens, and a rubber-elastic insert part, which has a hollow inner region which communicates with the outlet connection, is accommodated in the receiving space. The insert part has at least one air guide opening via which air can flow from the pump part into the inner region.
