Samples are obtd. by using the diamond grinding wheel which is formed by using the diamond abrasive grains having an average grain size of 2 to 6mum in cutting, rotating this grinding wheel at a spec of >=2000 to <=5000mm/min and feeding the dummy substrate at a feed speed of >=20m/min to <=80m/min. Consequently, the insulating layers of the cut surfaces are more hardly failed than the samples formed by using the abrasive grains varied in grain sizes. Magnetic insulation is thus assured and the magnetic permeability of the magnetic metallic films is improved.
