<P>PROBLEM TO BE SOLVED: To provide an electrostatic induction touch sheet being freely assembled without taking account of a physical relationship with an RFID antenna and an influence on RFID communication caused thereby, and an RFID device including the electrostatic induction touch sheet. <P>SOLUTION: An electrostatic induction touch sheet 5 in which a grounded loop circuit 11 is formed to enclose a sensor electrode 10, includes a resistive element 16 as a filter for preventing a shield current for suppressing a magnetic field for RFID communication from flowing to the loop circuit 11. The generation of the shield current of the loop circuit 11 is suppressed by the resistive element 16, so that the electrostatic induction touch sheet 5 is freely assembled without taking account of the physical relationship with an RFID antenna 4 and an influence on the RFID communication caused thereby. <P>COPYRIGHT: (C)2013,JPO&INPIT |
