Abstract
A method for manufacturing a laminated body includes: laminating an electromagnetic steel plate to form the laminated body; performing an annealing process on the laminated body; acquiring a before-annealing lamination thickness information on a thickness of the laminated body before performing the annealing process on the laminated body; and when the before-annealing lamination thickness information does not satisfy a before-annealing criterion which is predetermined, adjusting a lamination condition of the electromagnetic steel plate such that the before-annealing lamination thickness information satisfies the before-annealing criterion.
