Abstract
A compact Hall element having a high magnetic sensitivity, a wide measuring range and which is resistant to application conditions such as high temperatures or radiations, includes a rectangular recess formed in a surface layer of an insulator layer, a negative electrode for emitting electrons and a positive electrode for collecting the electrons provided on the surface of the insulator layer surrounding the recess, a gate electrode located on the bottom of the recess so that it faces the negative electrode, Hall electrodes that are provided on the surface of both sidewalls of the recess and which are parallel with the line connecting the centers of width of the negative and positive electrodes. All of these electrodes are disposed in a vacuum containment structure.
