Abstract: A light-emitting device including:



a light-emitting element; and
a lens joined to the light-emitting element,
wherein the light-emitting element has a rectangular light emission surface facing the lens,
wherein the lens includes: an opposing surface facing the light-emitting element; and a convex surface oriented in an opposite direction to the opposing surface, and
wherein as seen in a direction perpendicular to the light emission surface, a circumferential edge of the convex surface is circular, and, when a distance between a center of the convex surface and a center of the light emission surface is denoted by Δ (unit: μm); a length of a shortest edge of the light emission surface is denoted by L (unit: mm); a diameter of the circumferential edge of the convex surface is denoted by R (unit: mm); and R/L is denoted as r; formula (1):
