Abstract
A polarizing element includes: a substrate; a plurality of reflection layers that is arranged in a band shape at a predetermined interval on the substrate; dielectric layers that are formed on the reflection layers; and inorganic micro-particle layers that are formed on the dielectric layers by inorganic micro-particles having shape anisotropy in which a length of a diameter of the micro-particles in an arrangement direction of the reflection layers is longer than a length of a diameter of the micro-particles in a direction orthogonal to the arrangement direction of the reflection layers and has convex portions toward a side of a first adjacent reflection layer and a side of a second adjacent reflection layer.
