Abstract
To provide a light emitting device and a light emitting module which can suppress deterioration caused by light emitted from a light emitting chip, even in the case of using a light emitting chip emitted light of which has a short wavelength and in which deterioration of emission brightness and the like does not easily occur even if used for a long period of time.The device is characterized by including a container (20) which is formed of a transparent inorganic material and has a recessed opening, a light emitting chip (1) which is disposed in the recessed opening of the container (20) with a glass bonding member (4) interposed therebetween and in which a first conduction type layer (11), a light emitting layer (12), and a second conduction layer (13) are formed on a substrate (10), and a lid (21) which is formed of a transparent inorganic material and blocks the recessed opening of the container. The container (20) and the lid (21) are formed of quartz glass, optical glass containing boric acid and silicic acid, crystal, sapphire, fluorite or the like.
