PROBLEM TO BE SOLVED: To provide a position sensor manufacturing method capable of correcting out-of-synchronism more precisely than a temporal resolution of a signal processing circuit, or a position sensor. ! SOLUTION: A position sensor manufacturing method is adapted to manufacture a modulation/demodulation type position detection system 200 including a signal processing circuit 150 provided with an excitation signal generation part 101 for generating an excitation signal SS10 to be supplied to a position detection part 100 and a synchronism detection part 160 for demodulating a sensor output signal SS1 from the position detection part 100 in accordance with synchronism detection. Sensor output measurement means is included for measuring the sensor output signal SS1 obtained from the position detection part 100. On the basis of data obtained by a switching signal SS2 for sampling the sensor output signal SS1 and the sensor output measurement means, the excitation signal SS10 formed from a D/A converter |
