<p>Particularly, there is provided a magnetic sensor capable of preventing an occurrence of a chattering or the like to provide a stable operation and easily controlling a magnetic sensitivity depending on applications. The magneto-resistance element 8 is formed in a slender and longitudinal shape in which an element length L is greater than an element width W and the element width W is in the range of 1 µm to 5 µm. The element length L is in the range of 50 µm to 250 µm. Owing to the result, it is possible to easily control a coercive force Hc of the free layer with required magnitude. In addition, the coercive force Hc may be in the range of 5 Oe to 10 Oe (about 395 A/m to 790 A/m) by setting the element width W in the range of 1 µm to 5 µm.</p> |
