To provide a light-emitting device of better stage effects, by preventing movement of light-emitting liquid and changes of tints of emission from getting simplified.
The light-emitting device 10 includes: a production part 20 in which overflowing light-emitting liquid of given colors runs down from a first-production vessel 21 located at the topmost step to a third-production vessel 23 located at the lowermost step; a circulation route formed of piping provided with a first connecting tube 32, a second connecting tube 35 and a return tube 36 for sending back light-emitting liquid of the third-production vessel 23 to the first-production vessel 21; a pump 34 for sending the light-emitting liquid from the third-production vessel 23 to the piping; and an inputting part 33 inputting light-emitting liquid emitting light of other colors into the circulation route. The inputting part 33 includes: a first bottle B1 and a second bottle B2 with a top part open for storing light-emitting stock liquid and light-emitting reaction liquid, respectively, to be light-emitting liquid emitting light of other colors; a mixing vessel 31 for mixing the liquids; and an input control part as well as a motor 322 for reversing the two bottles up and down.
