ELECTRONIC TAG AND ITS MANUFACTURE

摘要

PROBLEM TO BE SOLVED: To provide an electronic tag where the surface part of film-like resin is melted and it is adhered to external resin at the time of molding an external part and the connection of the external part and film-like resin is highly reliable by combining resins satisfying a condition that melting point or softening point of film-like resin is lower than the molding temperature of resin of external part. SOLUTION: The internal part 35 of an electronic tag 20 is filled by means of film-like resin 34 and the filled internal part is set in a metallic mold 37. Resin 39 having compatibility is filled to film-like resin 34 in the metallic mold at temperature higher than the melting point or softening point of film-like resin 34 so as to form external resin 33. Thus, the face part of film-like resin 34 melts at the time of molding external resin 33 and it is adhered to external resin 33 and the electronic tag 20 with high reliability on connection between the external part and film-like resin 34 is obtained.
