Abstract: A light-emitting device includes: a substrate; a light-emitting element above the substrate; a plate-shaped light-transmissive member having a lower surface that faces the upper surface of the light-emitting element; and a covering member. The upper surface of the light-emitting element has a rectangular shape so as to have a first lateral side and a second lateral side opposite to each other. An upper surface of the light-transmissive member has a rectangular shape having a first lateral side and a second lateral side opposite to each other. In a plan view from above the light-emitting device, the first lateral side of the upper surface of the light-transmissive member is outside the first lateral side of the upper surface of the light-emitting element, and the second lateral side of the upper surface of the light-transmissive member is inside the second lateral side of the upper surface of the light-emitting element.
