Abstract
A wireless IC tag-attached metal medical instrument includes a metal medical instrument including a metal portion. The metal medical instrument is configured such that electric, magnetic, or electromagnetic field coupling is established between a resonant circuit and the metal portion when a wireless IC tag is fixed to the metal portion that includes the resonant circuit having an inductor with a spiral or helix shape that turns around a central axis more than one turn. In this configuration, the metal portion either emits a transmission signal with a frequency equal to a resonant frequency of an electromagnetic wave supplied from the resonant circuit or receives a reception signal having a frequency equal to the resonant frequency, and supplies the reception signal to the resonant circuit.
