摘要

A light-emitting device 100 includes: a light-emitting element; a light-transmissive member covering the light-emitting element; and a light-diffusing agent contained in the light-transmissive member and comprising hollow particles. The light-transmissive member has a first surface having irregularities according to the light-diffusing agent. The first surface of the light-transmissive member has a convex shape with a height gradually increased from a peripheral portion of the first surface toward a central portion of the first surface.
