A position detection device configured to detect a position of a moving member that moves back and forth in a predetermined moving direction is provided with an exciting coil arranged to extend in the moving direction along the moving member, and a detection coil that, by an action of a magnetic field generated by the exciting coil, can detect a position, in the moving direction, of a detection object portion provided on the moving member within a predetermined detection range. A plurality of the detection coils are arranged side by side in a direction perpendicular to an extending direction of the exciting coil. A plurality of the detection object portions are provided at different positions in the moving direction so as to respectively correspond to the plurality of the detection coils, and the respective detection ranges of the plurality of the detection coils are offset in the moving direction of the moving member.
