Claim 10:
11. The force sensor according to claim 1, wherein the first permanent magnet layer, the second permanent magnet layer and the magnetic tunnel junction are formed in a surface shape, a partial region, to which pressure is applied from outside, the second permanent magnet layer moves in a direction of the first permanent magnet layer, and, when a magnetic field strength formed between a partial region of the second permanent magnet layer and the first permanent magnet layer is formed to a preset strength or more according to a movement of the partial region of the second permanent magnet layer, the magnetic tunnel junction senses the pressure and an area, to which the pressure is applied, based on a total resistance value, which comprises a changed resistance value of a partial region of the magnetic tunnel junction corresponding to the partial region of the second permanent magnet layer, of the magnetic tunnel junction.
