PURPOSE:To detect stress over a wide range by improving the stress-magnetic characteristic of an amorphous magnetic alloy, by bonding other material to an amorphous magnetic alloy piece and preliminarily imparting compression strain to at least a part of the amorphous magnetic piece. CONSTITUTION:Compression strain is preliminarily applied to an amorphous magnetic alloy thin strip M by bonding a film having a thermal expansion (contraction) characteristic different from that of an amorphous magnetic alloy to the surface of the amorphous magnetic alloy or connecting the same to said alloy in a contact state. By this method, the stress-magnetic characteristic of the amorphous magnetic alloy is markedly improved and a range of dynamic quantity detection limit is enlarged and, if said alloy is mounted to a shaft 1 and the magnetic change thereof is read in a magnetic detection part, the stress of the shaft 1 can be accurately measured.
