Abstract
To prevent cracks on a sealing glass or a substrate in a LED package in which a light-emitting device is sealed with a sealing glass. The LED package comprises a substrate, a LED mounted on the substrate, and a sealing glass for sealing a LED formed on the substrate. A wiring pattern being connected to an electrode of the LED is formed on the surface of the substrate. A back electrode pattern is formed on the rear surface of the substrate. A columnar via is formed in the substrate. Thus, the wiring pattern on the surface of the substrate and the back electrode pattern on the rear surface of the substrate are electrically connected. A softening point of the substrate is set higher than softening point of the sealing glass.
