ABSTRACT:
A pressure sensor having the structure wherein an amorphous magnetic alloy member or members are secured to both of a deforming part which is distorted by a pressure and a non-deforming part which is not distorted by a pressure and elements for detecting the change of a permeability of the amorphous magnetic alloy are respectively disposed at each of the amorphous magnetic alloy members, can measure the magnitude of an applied pressure with high accuracy while suppressing a drift of the output accompanied with the change of a temperature.
