1. An optical multilayer structure comprising:

  • a transparent substrate made of a non-metallic material;

    a first transparent layer in contact with the transparent substrate;

    a gap portion having a changeable size capable of causing an optical interference phenomenon; and

    a second transparent layer,the first transparent layer, the gap portion, and the second transparent layers being stacked in accordance with this order on the transparent substrate,wherein when a refractive index of the transparent substrate is ns, a refractive index of the first transparent layer is n1, and a refractive index of the second transparent layer is n2, the relation of ns<

    n1, and the relation of n1>

    n2 are satisfied.
