Abstract
A wavelength conversion apparatus according to an aspect of the present disclosure includes a wavelength conversion layer that converts excitation light in terms of wavelength and an optical array layer formed of a plurality of cells each having a first surface on which light as a result of the wavelength conversion performed by the wavelength conversion layer is incident and a second surface via which the light exits. The optical array layer has a reflection surface that extends from the first surface to the second surface, is located at an interface between the cells adjacent to each other, and reflects the light.
