Abstract
An LED device is provided which includes a substrate, an LED element disposed on the substrate, an inorganic glass molded body disposed at a position where all or a part of the light which is emitted from the LED element passes through, a first bonding portion that is provided in contact with the substrate and bonds the substrate and the inorganic glass molded body, and a second bonding portion provided between the LED element and the inorganic glass molded body. The LED element is shielded from the outside air by the substrate, the inorganic glass molded body and the first bonding portion. A material which forms the second bonding portion contains a condensation polymerization-type silicone resin. A distance between the LED element and the inorganic glass molded body is 0.1 mm or less.
