Abstract: The present invention relates to a composite RF tag for transmitting and receiving information using an electromagnetic induction method, comprising a magnetic antenna mounted with an IC, and a resin layer formed around the magnetic antenna, wherein the magnetic antenna comprises a central core formed of a magnetic material and a coil-shaped electrode material disposed around the core. The RF tag according to the present invention comprises the magnetic antenna surrounded by the resin, and therefore can provide a composite magnetic RF tag which can minimize adverse influence by surrounding water or metals in view of maintenance of tools or parts to which the composite RF tag is mounted, and is free from occurrence of any failure or cracking.
