Provided is a position sensor excellent in the linearity of a coil impedance. This position sensor includes a cylindrical detection coil, a core movable in the detection coil, a signal processing circuit for converting the impedance change of the detection coil into an electric signal, and a shield member arranged around the detection coil. The shield member is a cylindrical member having a first inner surface enclosing an axial section of the detection coil, and a second inner surface enclosing another axial section of the detection coil, such that the distance between the second inner surface and the detection coil is made shorter than the distance between the first inner surface and the detection coil.
