Abstract:
1. A method for producing a stress impedance effect element, the method comprising: forming a groove in an elastic thin substrate; forming electrodes across the groove; installing a magnetostrictive amorphous thin wire in the groove, the magnetostrictive amorphous thin wire having a thermal expansion coefficient equal to that of the elastic thin substrate; connecting opposite ends of the magnetostrictive amorphous thin wire and the respective electrodes by ultrasonic bonding, the electrodes formed under the magnetostrictive amorphous thin wire; and bonding together the magnetostrictive amorphous thin wire installed in the groove and the elastic thin substrate by applying an insulating adhesive such that the insulating adhesive crosses over the magnetostrictive amorphous thin wire.
