Abstract
A light-emitting device includes: a light-emitting element; a coating member that covers the light-emitting element; and two external connection electrodes exposed form a first surface of the coating member. Each of the external connection electrodes includes an electrode buried in the coating member; and a metal layer formed on the electrode. A surface of each of the metal layers is exposed from the first surface of the coating member. The first surface of the coating member includes a plurality of grooves between the external connection electrodes.
