Abstract: A phosphor member disclosed in one embodiment includes: a phosphor portion including a first surface and a second surface; and a surrounding portion connected to an outer edge of the first surface and connected to an outer edge of the second surface. In a plan view viewed in a direction perpendicular to the first surface, the first surface has a shape including a first region with a width in a second direction perpendicular to a first direction, the width in the second direction increasing along the first direction. A maximum width of the second surface in the second direction is greater than a minimum width of the first surface in the second direction and less than a maximum width of the first surface in the second direction.

Abstract: A light-emitting device includes first and second light-emitting elements, upper submounts, and a lower submount. The upper submounts include a first submount having a first upper surface and a first lateral surface located on a same side as an emission end surface of the first light-emitting element, and a second submount having a second upper surface and a second lateral surface located on a same side as an emission end surface of the second light-emitting element. In a top plan view, the first lateral surface is located forward relative to the second lateral surface, and the emission end surface of the first light-emitting element is located forward relative to the emission end surface of the second light-emitting element. At least a portion of the first lateral surface is protruded forward relative to an edge along which an upper surface and a lateral surface of the lower submount meet.
