Abstract
A radio frequency IC tag is provided which is excellent in weatherability, dustproofness, waterproofness, and static protection and capable of making a communication distance long even though each antenna section is made small in configuration. A first antenna equipped with an IC chip is formed on an upper surface of a first spacer. A second antenna is formed on a lower surface of a top cover. A second spacer is shaped in hollow form. The first spacer and the top cover are disposed on both sides of the second spacer with the first antenna and the second antenna being opposite to each other. Each of the first spacer, the second spacer and the top cover is formed of a synthetic resin. Thus, the IC chip and each antenna section are not exposed to the outside and hence weatherability is enhanced.
