ABSTRACT:
A mechanical quantity sensor element making use of stress-magneto effect of noncrystalline magnetic alloy. Compression strain is preliminarily given to a thin belt made of noncrystalline magnetic alloy by carrying out treatment of applying an external force onto a surface of the thin belt. Suitable methods for applying the external force include; surface grinding by means of abrasive cloth or paper, shot-peening in which spherical fine grains are impinged onto a surface of a thin belt, stroking work in which a surface of a thin belt is scrubbed by means of a scrubber piece made of synthetic resin, rubber or other material, and the like.
