Abstract
A production apparatus 100 includes a punch 12, a blanking die 14, a first holding part 16, a second holding part 18, and a heating part 20. A plurality of core sheets 1a is cut out from a steel strip 1 by the punch 12 and the blanking die 14, an outer peripheral portion of a plurality of core sheets 1a, which has been cut out, is pressurized laterally by the first holding part 16 and the plurality of core sheets 1a is pressurized downward by the punch 12, and the plurality of core sheets 1a pressurized downward by the punch 12 is heated by the heating part 20 while being held in the second holding part 18. The first holding part 16 holds the plurality of core sheets 1a at a temperature lower than a softening temperature of the adhesive layer 11b, and the heating part 20 heats the plurality of core sheets 1a held in the second holding part 18 to a temperature higher than or equal to the softening temperature.
