摘要： The magnetic sheet according to the present invention includes a resin and soft magnetic particles contained in the resin. The soft magnetic particles characteristically contain crystallites in an amorphous phase in a relatively small amount. The magnetic sheet can be obtained by producing soft magnetic particles consisting of an amorphous phase, producing a magnetic sheet containing the soft magnetic particles, and producing crystallites in the amorphous phase by annealing the magnetic sheet at a temperature of approximately the glass-transition temperature or approximately the crystallization temperature of the material constituting the soft magnetic particles.
