Abstract
To provide a compact and low-cost glass antenna in which an antenna position can be easily recognized by emitting a light near the antenna position, and thus a passerby or the like can easily grasp the position when he or she holds up a tag. The glass antenna has plate-like glasses 11A and 11B, antennas 12A and 12B provided on the plate-like glasses 11A and 11B, and a light emitting unit 16a that is provided so as at least a part thereof to be overlapped with the antennas as seen from the direction that the antennas 12A and 12B are directed, and scatters the light guided by the plate-like glasses 11A and 11B to emit light in the vicinity of the antenna.
