Zusammenfassung:Provided is a light-emitting device having a plurality of light-emitting elements with high operation stability and light extraction efficiency. The light-emitting device includes: a light-emitting element; a translucent member which is disposed on the light-emitting element and has a columnar first portion having a bottom surface opposed to an upper surface of the light-emitting element, a second portion formed continuously with the first portion on the first portion and narrowed upward, and a columnar third portion formed continuously with the second portion on the second portion; and a reflective member configured to cover the side surfaces of the translucent member. In this light-emitting device, the height of the first portion of the translucent member in a direction perpendicular to the bottom surface thereof is ⅙ or more the height of the translucent member in the direction perpendicular to the bottom surface.
