A planar conductor device and RFID chip are folded to create a coil to form an RFID tag. The result is the formation of a solenoid coil, not planar, which allows the device to be placed against metal. Specifically, the planar structure is folded into a concertina fold. After folding, a spiral conductor is formed in the Z direction, forming a coil with the RFID chip connected to both ends. This structure operates as a resonant RFID tag.

An RFID tag board includes an insulating substrate provided with a first surface conductor, a second surface conductor, a short-circuit part through conductor, a capacitance conductor, a capacitance part through conductor, a first electrode and a second electrode. The short-circuit part through conductor electrically connects the first surface conductor and the second surface conductor. The capacitance conductor faces at least part of one of the first and second surface conductors to form a capacitance element. The capacitance part through conductor electrically connects the capacitance conductor and the other one of the first and second surface conductors. First and second conductors of the capacitance element are electrically connected to the first and second electrodes, respectively, not via the short-circuit part through conductor. A distance from the first electrode to the short-circuit part through conductor is shorter than a distance from the second electrode to the short-circuit part through conductor.
