A coin detection antenna includes a substrate and a plurality of air core coils of track shape including a wiring pattern provided on the substrate. The plurality of air core coils is disposed along short-side directions of air cores of the plurality of air core coils such that a smallest coin of coins to be detected crosses at least one of centerlines of the air cores even when the smallest coin is located at any location in a detection range.
