Patent ID: 8366294

Claim:
A light-emitting device comprising: a container having a concave portion; a metal conductor portion provided so as to have one edge exposed to the concave portion of the container and have the other edge exposed to outside of the container; and a light-emitting element attached to one surface of the metal conductor portion exposed to inside of the concave portion, the light-emitting element being electrically connected to the metal conductor portion, wherein the container includes: a first container portion provided so as to cover a region of the concave portion to which the metal conductor portion is not exposed, the first container portion forming the concave portion together with the metal conductor portion; and a second container portion contacting the other surface of the metal conductor portion without being exposed to the concave portion, the second container portion accommodating the first container portion, wherein the first container portion is set to have higher light reflectivity for light emitted from the light-emitting element than the second container portion, and the second container portion is set to have higher thermal conductivity for heat conducted from the light-emitting element than the first container portion.
