    • A film composed of a metal or a semimetal is formed on a surface of a soft magnetic powder including iron and oxygen (in step S102). In this case, a silicon-containing film is desirably formed on a surface of the film. Next, compaction is performed on the soft magnetic powder, so that a green compact is obtained (in step S103). Since the film is a metal film or a semimetal film having a high ductility, the density of the green compact produced by the compaction can be higher, and generation of damage, such as cracks or the like, can be prevented in the film. The effects can be also obtained in a case of formation of the silicon-containing film. Next, the green compact is subjected to heating, so that a surface and an interface of the soft magnetic powder of the green compact are oxidized, so that an insulation film is formed (in step S104). Generation of eddy current loss can be prevented by the oxide film. As a result, productivity and magnetic properties can be improved.
    • 在包含铁和氧的软磁性粉末的表面上形成由金属或半金属构成的膜(步骤S102)。 在这种情况下,希望在膜的表面上形成含硅膜。 接着,对软磁性粉末进行压实,得到生坯(步骤S103)。 由于膜是具有高延展性的金属膜或半金属膜,所以通过压实产生的压坯的密度可以更高,并且可以防止在膜中产生诸如裂纹等的损坏。 在形成含硅膜的情况下也可以得到效果。 接下来,对生坯进行加热,使得生坯的软磁性粉末的表面和界面被氧化,形成绝缘膜(步骤S104)。 可以通过氧化膜防止产生涡流损耗。 结果,可以提高生产率和磁性。
