Abstract
A RFID tag having a loop antenna comprises: a flat plate shaped dielectric member 51; first and second loop antenna patterns 52, 53 that are formed on a first and second surface of the dielectric member 51 so that they are separated from each other by a specified space, and so that each is continuous from the first surface to the second surface of the dielectric member 51; and an IC chip 54 that electrically connects the first and second loop antenna patterns 52, 53 on one of the surfaces.
