発明の名称 (英語) SENSOR ELEMENT WITH TEMPERATURE COMPENSATING FUNCTION, AND MAGNETIC SENSOR AND ELECTRIC POWER MEASURING DEVICE WHICH USE SAME コモンズ
発明の概要(英語) A magnetoresistance effect magnetic sensor has a problem that the sensitivity thereof as a sensor lowers because the magnetic characteristic of a magnetic film itself lowers due to an increase in surrounding temperature. A sensor element characterized by comprising: a magnetic film having a magnetoresistance effect; a pair of electrodes facing each other with the magnetic film therebetween in order to pass a current through the magnetic film; a longitudinal bias magnetic field application magnet for generating a first bias magnetic field in a direction in which the electrodes face each other; and a lateral bias magnetic field application magnet for generating a second bias magnetic field in a direction perpendicular to the longitudinal bias magnetic field application magnet, and in that the temperature characteristic of the longitudinal bias magnetic field application magnet is larger than the temperature characteristic of the lateral bias magnetic field application magnet.
