摘要：
A method of producing a soft magnetic material includes the steps of preparing soft magnetic powder containing a plurality of soft magnetic particles etching the soft magnetic powder to remove surfaces of the soft magnetic particles and, after the etching step, heat-treating the soft magnetic powder in a finely divided state at a temperature of not less than 400° C. and not more than 900° C. By this method configured as above, desired magnetic characteristics can be obtained.
