Abstract

An electromagnetic induction type processing apparatus includes a coil and a functional device. The coil is configured to generate electromotive force from a magnetic field supplied from the outside. The functional device is configured to operate with the electromotive force and containing conductive substance having a conductivity with which eddy current to be generated in the conductive substance by the magnetic field supplied from the outside is suppressed such that the lowest electromotive force for operation of the functional device is assured regardless of a magnetic field generated by the eddy current and acting in the opposite direction to that of the magnetic field supplied from the outside.

Claims
