1. A sensor apparatus, comprising:

  • a first member;

    a second member relatively movable in a first direction with respect to the first member; and

    a detection mechanism including an elastic member arranged between the first member and the second member, a support that is provided between the first member and the elastic member and forms an air layer between the first member and the elastic member, the air layer having a thickness changed by an elastic deformation of the elastic member, and an electrode pair that forms a plurality of capacitances including a capacitance component changed in accordance with a change of the thickness of the air layer, the detection mechanism being configured to output a detection signal on a movement amount of the second member in the first direction based on a change of a combined capacitance of the electrode pair.
