In a rotating machine, a plurality of laminated electromagnetic steel
sheets constitutes at least one of a stator and a rotor and a plurality
of permanent joining portions to unit each of the laminated
electromagnetic steel sheets to form a corresponding one of the stator
and the rotor, the plurality of permanent joining portions being set to
be located at positions at which an integration value of a magnetic flux
density with respect to a plane enclosed with the permanent joining
portions is always zeroed.
