Method for producing stress impedance effect element and that element

摘要

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