Abstract
A laminated core includes a laminated body, clamping plates and holding members. The laminated body includes a plurality of amorphous alloy plates, which are stacked one after another in a stacking direction such that each adjacent two of the plurality of amorphous alloy plates directly contact with each other. The clamping plates contact opposed end surfaces, respectively, of the laminated body in the stacking direction. A thickness of each of the first and second clamping plates in the stacking direction is larger than that of each of the plurality of amorphous alloy plates. Each holding member contacts with the clamping plates and maintains a predetermined space between the clamping plates while the laminated body is clamped between the clamping plates.
