器。 A permanent magnet that moves up and down to follow the deformation of the diaphragm, a first support that supports the permanent magnet, and an electrical resistance value that changes according to changes in a magnetic field that is provided opposite the permanent magnet. It has a magnetoresistive element and a second support that supports the magnetoresistive element, and these first and second supports are provided so that they can move up and down relative to each other and are rotatable about the up and down direction. In addition, a pressure transducer characterized in that these supports can be fixed at arbitrary positions.
