PROBLEM TO BE SOLVED: To provide a magnetic field detector that is less sensitive to variations in magnetic characteristics of a magnetic material in a magnetic element. ! SOLUTION: The magnetic field detector comprises: an excitation signal generation unit 2018 generating an alternation signal; an excitation signal adjustment unit 2017 generating an alternation current from the alternation signal, and generating an excitation current to be applied to an excitation detection coil on the basis of the alternation current; an alternation signal adjustment unit 2019 connected to an output of the excitation signal adjustment unit, adjusting the intensity of the excitation current outputted by the excitation signal adjustment unit 2017, and outputting a detection signal; a detection signal comparison unit 2013 detecting a first time when the detection signal exhibits a predetermined positive voltage and a second time when the detection signal exhibits a predetermined negative voltage; and a data signal conversi |
