High light transmission efficiency is achieved in an electroluminescence device (1) without lowering the durability of the device. The electroluminescence device (1) includes: electrodes (11, 16); a plurality of layers (13 to 15) that are deposited one on another between the electrodes (11, 16); and a light emitting region (14) between the plurality of layers (13 to 15). The light emitting region (14) emits light by application of an electric field between the electrodes (11, 16). At least one microparticle (20) that induces plasmon resonance on the surface thereof by the light emitted from the light emitting region (14) is arranged in the vicinity of the light emitting region (14) or in the light emitting region (14). The microparticle (20) is a core-shell-type microparticle including at least one metal microparticle core (22) and an insulation shell (21) that covers the at least one metal microparticle core (22).
