A position detection device for detecting a position of a moving member moving forward and backward in a predetermined moving direction is provided with a detection object attached to the moving member, a substrate provided with an excitation coil being positioned to face the moving member and parallel to the moving direction of the moving member for generating a magnetic field in an area including the detection object, and a detection coil being interlinked with a magnetic flux of the magnetic field, a power supply unit for supplying an alternating current to the excitation coil, a calculation unit that calculates the position of the moving member based on an output voltage of the detection coil, and a spacing fluctuation suppression structure that suppresses fluctuations in a spacing between a facing surface facing the detection object and the detection object in the substrate.
