PROBLEM TO BE SOLVED: To provide a method of inhibiting electromagnetic coupling among coils for preventing the coils from electromagnetically coupling with one another. SOLUTION: A noise inhibiting sheet is stuck to a surface of coil winding on each of a plurality of coils provided on a circuit board. With this method, the noise inhibiting sheet present on the winding surface of each coil can inhibit interference by electromagnetic coupling of the adjacent coils. Therefore, a high impedance control signal can be detected even if a desired control signal is to be detected using the coil. COPYRIGHT: (C)2008,JPO&INPIT
