<p>[PROBLEMS] To provide a magnetic detecting device which adjusts especially a resistance value of a sensor section having a sensor pattern provided with a magnetoresistive effect film and an electrode section, without increasing the size of the sensor section, and suppresses deterioration and variance of magnetic characteristics to be small. [MEANS FOR SOLVING PROBLEMS] The magnetic detecting device is provided with a sensor section (20) having a sensor pattern (35) wherein end sections of a plurality of magnetoresistive effect films (60-65) in the longitudinal direction are connected through returning sections (37), and electrode sections (16, 19) formed on the both end sections of the sensor pattern (35) in the longitudinal direction. The nonmagnetic conductor (66) is electrically connected over from an upper surface (61a) of one magnetoresistive effect film (61) to an upper surface (62a) of the other magnetoresistive effective film (62), which face each other through the returning section (37). Thus, a resistance value between the electrode sections (16, 19) can be adjusted without increasing the size of the sensor section (20), and deterioration and variance of magnetic characteristics can be suppressed to be small.</p> |
