In a magnetoresistive effect element, at least one of electrodes for supplying a current perpendicularly to the film plane of a magnetoresistive effect film is narrower than the distance between bias-applying films. The sensitivity of the magnetoresistive effect film is lower in regions thereof near the bias-applying films due to an intensive bias magnetic field from the bias-applying films. However, the electrodes are disposed in an inner region having a high sensitivity avoiding those regions with a lower sensitivity to ensure a high sensitivity. The electrodes disposed on and under the magnetoresistive effect film are pillar-shaped to concentrate the sense current such that the sense current can be concentrically supplied exclusively to the region with the high sensitivity.
