It is an object to provide a package for a magnetic circuit, with which a leakage
magnetic field escaping from an aperture of a magnetic circuit is reduced and the
magnetic attraction acting on the packaging plates is lowered, thus reducing the
number of packaging work steps. There are provided a packaging plate for a permanent
magnet-type magnetic circuit, the packaging plate comprising at least one non-magnetic
layer and at least one magnetic layer; and a method for packaging a permanent magnet-type
magnetic circuit, comprising a step of shielding at least a portion of an aperture
of a permanent magnet-type magnetic circuit using at least one packaging plates.
