Abstract
A wavelength conversion apparatus includes a base having a first surface, a wavelength converter disposed at a first surface side of the base and configured to convert first light having a first wavelength band into second light having a second wavelength band different from the first wavelength band, the wavelength converter including a light exiting surface which is provided at the side opposite from the base and via which the second light exits, a liquid metal disposed between the base and the wavelength converter, and a first restrictor holding the wavelength converter at the base and restricting a position of the wavelength converter in a first direction along a normal to the light exiting surface.
