PROBLEM TO BE SOLVED: To provide a magnetic detection device capable of maintaining accurate detection accuracy even when temperature offset is generated. SOLUTION: In this magnetic detection device, a magnetoelectric conversion element is constituted of at least six segments arranged symmetrically at prescribed pitches with respect to the center line of a magnet in the rotation direction of a magnetic moving body, and the first and second bridge circuits for generating outputs following rotation of the magnetic moving body to the magnet center are constituted, and the third bridge circuit for generating an output following rotation of the magnetic moving body is constituted. The device has a characteristic wherein a comparison level of a comparator circuit for performing waveform shaping of the first and second bridge circuit differential output signals is adjusted by the third bridge circuit output signal.
