Abstract

A light-emitting apparatus includes: a ceramic substrate; a light-emitting element mounted on the ceramic substrate; a sealing member sealing the light-emitting element; a buffer layer formed on the ceramic substrate and surrounding the light-emitting element; and a dam member, at least a portion of which is on a top surface of the buffer layer and which is for blocking the sealing member. The dam member is formed in such a way that one end of the dam member which faces the sealing member and is closer to the light-emitting element than the opposite end of the dam member is in contact with the ceramic substrate while the opposite end is out of contact with the ceramic substrate.
