Abstract
A tilt sensor for a vehicle steering shaft includes a base resistive element layer formed in an opposed contact with a base plate surface. A plural layer structure is provided with a protective resistive element layer constructed by at least one layer formed on the base resistive element layer and an uppermost layer of the volume inherent reistance of the protective resistive element layer is higher than the volume inherent resistance of the base resistive element layer. The volume inherent resistance of the protective resistive element layer is from 2 to 500 times the volume inherent resistance of the base resistive element layer.
