Abstract
An object of the present invention is to improve a mechanical strength and to ensure a low magnetic loss without using a supporting member even when amorphous ribbons are used for an inner core. To attain the object, a stationary induction apparatus core of the present invention includes an inner core formed from the amorphous ribbons and outer cores formed from silicon steel sheets, the outer cores being disposed on two sides of the inner core in a depth direction as opposed to a standing direction of the inner core in such a manner as to sandwich the inner core therebetween.
