To provide a contactless electronic tag having mass productivity and a structure that has extended a communication range and a directionality of communication. In the structure, a wave director and a reflector having a planar pattern in the shape of an approximate L letter and formed in the same dimensioned planar pattern are pasted to an adhesive surface of a label seal in a point symmetric manner via an inlet 1 in between on the adhesive surface of the label seal so that the wave director and the reflector are arranged in close proximate to and along the periphery of the label seal. Due to this, it becomes possible to improve the mass productivity of the contactless electronic tag and efficiently receive radio waves radiated from an antenna of a reader while reducing a circular polarization loss.
