Abstract
There is provided an amorphous core annealing method in which the annealing temperature distribution within an iron core is regulated so that deterioration in the magnetic properties, which is caused by unevenness of the annealing temperature within the core, can be suppressed, and the annealing time can be shortened. In order to regulate the annealing temperature distribution within the amorphous core at the annealing time, a heater functioning as a heat source is held between laminated thin-film amorphous materials of an iron core, and annealing is performed. By uniformly regulating the annealing conditions within the core, deterioration in the magnetic properties, which is caused by unevenness of annealing, can be suppressed to a minimum. Also, an iron core of a special specification, for example, a core having a low core loss, or a core having a high magnetroresistance, can be manufactured by using different annealing conditions within the iron core.
