Abstract: A position detection device includes a substrate disposed to face a displaceable detection object, a transmitting coil provided in the substrate, a first receiving coil and a second receiving coil which are disposed inside the transmitting coil in a normal direction with respect to a surface direction of the substrate, and a signal processing unit that derives a displacement amount of the detection object in view of a gap between the detection object and the substrate, based on a first characteristic value of the first receiving coil and a second characteristic value of the second receiving coil.
