Claims

[Scope of utility model registration request]

a loop-shaped coil and connect it to both ends of this loop-shaped coil”
and a resonant tag attached to a product, in which the loop-shaped coil and the capacitor are grouped together in a transparent manner, and a resonant tag attached to a product includes a small part of the loop-shaped coil (both at a position including the connection part with the capacitor). . A resonant dug, characterized in that an opaque covering member is arranged so as to overlap the loop surface side of the loop-shaped coil.
