Abstract
It is an object of the invention to provide an electromagnetic wave shield for attenuating a electric far field while suppressing the attenuation of the vicinal magnetic flux of an electromagnetic wave discharged from a high frequency electromagnetic wave generator.An electromagnetic wave shield according to the invention comprises a plurality of electric conductors, a ground contact for carrying out a connection to a ground, and a lead wire for connecting the electric conductors to the ground contact, the electric conductors being electrically connected to the ground contact through the lead wire, wherein the electric conductors are provided in such a manner that a path reaching the ground contact through the lead wire from an optional point of each of the electric conductors is uniquely determined.
