Abstract
The present invention provides an RFID tag to be applied to a container for holding liquid. To achieve a good communication distance regardless of the presence or absence of liquid, the RFID is applied to a container for holding liquid, and includes an IC chip on which identification information is recorded, and an antenna made of a loop-shaped conductor connected to the IC chip, and the antenna has a T-shaped opening in which the conductor is not formed.
