If the magnetic fine particles are magnetic powder or magnetic flakes made of sendust, the saturation magnetic flux density and magnetic permeability of the magnetic layer 12 containing these as constituent elements are increased, so that the magnetic flux is captured by the antenna through the magnetic layer. It becomes easy to be done.

  Note that the shape of the magnetic fine particles constituting the magnetic layer 12 does not have to be either powdery or flat. The magnetic layer 12 may be mixed with powdered magnetic fine particles and flat magnetic fine particles, and even when magnetic fine particles having different shapes are mixed, the magnetic sheet 10 exhibits a sufficient effect. .

  In this state, when the antenna of the information writing / reading device is opposed to the non-contact type IC card 31 or the non-contact type IC card 33, the non-contact type IC card 31 or the non-contact type IC card 31 or Information can be written to / read from the contact IC card 33.

  On the other hand, even if the antenna of the information writing / reading device is opposed to the non-contact type IC card 31 or the non-contact type IC card 33, the non-contact type IC card 32 held on the magnetic sheet 10B is formed on the two metal substrates 11. Since they are sandwiched, information is not written / read to / from the non-contact type IC card 32.

  When the non-contact type IC card 31 held on the magnetic sheet 10A and the non-contact type IC card 33 held on the magnetic sheet 10C are used, or the non-contact type IC card 32 held on the magnetic sheet 10B and the magnetic sheet When using the non-contact type IC card 33 held in 10C, it can be used in the same manner by changing the binding order of the magnetic sheets 10.
