A light-emitting device includes a case including a first substrate and a sidewall on the first substrate, a light-emitting, element that is mounted on the first substrate in a region surrounded by the sidewall and includes a second substrate and a crystal layer, the light-emitting element being formed rectangular in a plane viewed in a direction perpendicular to the first substrate, and a low-refractive-index layer that is located between the light-emitting element and the sidewall and has a smaller refractive index than the second substrate. A side surface along a longitudinal direction of the second substrate is provided with a tapered portion on a side of the first substrate.
