摘要： A sensor manufacturing method is a method for manufacturing a sensor including a generator that generates a predetermined detection target, a detector that detects the detection target generated by the generator, and a motion body that performs motion in the area in between the generator and the detector. In the method, the generator and the detector are positioned opposite to each other by either curving or bending a substrate including a first portion having the generator installed thereon and a second portion having the detector installed thereon that are formed in an integrated manner, and the substrate and the motion body are made to perform relative movement in such a way that the motion body enters the area in between the generator and the detector.
