Semiconductor light-emitting element and light-emitting device

A light-emitting device, comprising:

• a package with electrodes;
• a semiconductor light-emitting element that has an electrode portion electrically connected to the electrodes and emits ultraviolet light with a wavelength of not more than 355 nm;
• and
• a sealing resin that seals the semiconductor light-emitting element and is in contact with the electrode portion,
• wherein the sealing resin has an alkyl group or a functional group containing carbon in a side chain, and the electrode portion is formed by laminating any one or more of a metal providing passivity against organic acids, a metal having a lower ionization tendency than hydrogen and a conductive oxide film, and does not include a layer formed of a material that does not provide passivity against organic acids, has higher ionization tendency than hydrogen and is not a conductive oxide film.
