摘要： An antenna coil includes an air-core coil wound helically in a plane and a plate magnetic core member inserted in the air-core coil to be approximately parallel with a plane of the air-core coil. The magnetic core member is formed by a soft magnetic metal, an amorphous or ferrite, or a composite member of a powder, flake and plastic, or rubber. The magnetic core member is formed by performing an injection molding operation or a compressing molding operation of the composite member. Alternatively, the magnetic core member is a magnetic coating formed by applying and drying the composite member. A non-magnetic conductive plate that has a conductivity is layered on a surface of the air-core coil through which the magnetic core member is inserted. The conductive plate is made of a copper, a copper alloy, an aluminum or an aluminum alloy having 0.01 to 2 mm thickness. The antenna coil is operated by relatively high frequency while it is rigid relatively.

摘要： A soft magnetic member (5) which is formed by a composite of an organic object such as a metal grain powder, a flake, a ferrite grain powder, a ferrite, an amorphous film or a layered member of the amorphous film with 10 mm or lower thickness so as to satisfy a predetermined relationship with an antenna area, a circumference length, and a magnetic transmission ratio and a conductive member (7) which has approximately 10×10−8 Ωm or lower, more preferably 0.005 Ω or lower initial resistance are provided between the an antenna coil which is formed at least one loop and a metal surface (6) of the conductive member such as a metal casing. The magnetic flux which invades into the conductive object is blocked by the soft magnetic member (5) and the conductive member (7) so as to restrict the influence thereof. By doing this, it is possible to provide a reader/writer antenna for an RFID system in which it is possible to restrict a variance of a resonating frequency and an increase in a loss even if it is disposed so as to contact the conductive object such as a metal casing.

The wrist watch containing tag of this invention comprises a watch case having a ring-shaped frame, a glass lid, and a bottom lid; a drive section which is accommodated inside the watch case; a display section for displaying time which is driven by the drive section; and an RFID tag which is accommodated inside the watch case and comprises an antenna and an IC chip; the ring-shaped frame and/or the bottom lid having at least one slit therein, and the antenna comprising a wound coil which runs along the inner face of the ring-shaped frame so as to surround the drive section. The slit is filled with a nonconductive resin, affixing the opposing cutaway planes together.
