PROBLEM TO BE SOLVED: To provide an in-vehicle ATC receiver suitable for receiving signals in specific two frequency bands with high sensitivity. SOLUTION: The in-vehicle ATC receiver 1 includes receivers 11a and 11b that receive transmission signals transmitted through tracks 8a and 8b, an adding circuit 12 that adds received signals, and a reception circuit 14 for carrying out detection and amplification processing on received signals. A bipolar resonance circuit 13 is added to the outputs of the receivers 11a and 11b. Thus, such a reception characteristic that the maximum value is present in a first frequency band and a second frequency band is obtained, and signals in specific two frequency bands can be received with high sensitivity.
