A radio frequency identification tag includes an antenna element embedded in a thin plate made of a resin material. A radio wave reflector made of metal is embedded in the thin plate. The radio wave reflector extends in parallel with the antenna element. The radio wave reflector serves to reflect radio wave penetrating into the thin plate. The reflected radio wave is directed to the antenna element. The radio wave reflector serves to increase the received amount of the radio wave at the antenna element. The radio frequency identification tag thus significantly contributes to increase of a communication range. Moreover, since the radio wave reflector is embedded in the thin plate, the radio frequency identification tag can be utilized in conventional applications or purposes as ever. The addition of a reflector outside the tag inevitably restrains the applications of the tag.
