ABSTRACT:
A light-emitting module having a light-emitting efficiency. The light-emitting module that emits light includes a semiconductor light-emitting element operable to emit light, and a sealing member operable to seal the semiconductor light-emitting element with materials that transmit the light emitted from the light-emitting module, in which the semiconductor light-emitting element includes a sapphire substrate that transmits light toward the sealing member to send the transmitted light from a facing face facing the sealing member and forms a sub-wavelength grating for reducing reflection of light on the facing face in grid periods shorter than a wavelength of the light transmitted through the sapphire substrate, and a semiconductor layer that is formed on a rear face of the facing face in the sapphire substrate by crystal growth and emits light toward the sapphire substrate.
