Abstract
A magnetic sensor includes a sensing chip having a magnetoresistive element for sensing a magnetic vector and a magnet for biasing the magnetic vector sensed by the magnetoresistive element. The sensing chip senses change in the magnetic vector for detecting a behavior of a magnetic body based on a variation of a resistance value of the magnetoresistive element when biasing of the magnetic vector is caused by the magnet in cooperation with the magnetic body that is in motion in a proximity of the sensing chip, and the magnet takes a shape of a flat cylinder that houses the sensing chip in a hollow space bored therein.
