Zusammenfassung:PROBLEM TO BE SOLVED: To provide an in-vehicle receiver in which noise can be canceled excellently through simple processing while reducing devices for noise cancellation.SOLUTION: In a radio receiver 1 which is mounted in a vehicle and comprises a broadcast wave antenna 10, under a bottom 31 of a car body 30 that is a place which a radio wave is more unlikely to reach than the broadcast wave antenna 10, a noise detection antenna 21 is installed being electrically spaced apart from the car body 30, and a voltage between the car body 30 and the noise detection antenna 21 is detected by a voltage detection circuit 22. The voltage detected by the voltage detection circuit 22 is regarded as a noise, and the noise is canceled from a radio wave received by the broadcast wave antenna 10.
