Plural magnetic sheets () are laminated in circumference direction to form a cylindrical laminated core. Magnetic sheets () adjacent to each other have coupling point () at an upper section or a lower section and gap () on an opposite side of coupling point (). Coupling point () is prepared at upper section (), then lower section (), and upper section () then lower section () alternately. This structure allows assembling a radial laminated core with ease.
