The purpose of the present invention is to provide a chemiluminescent aerosol product that can easily form an expected quantity of a chemiluminescent composition which exhibits excellent storage stability, is stably self-held for a long period of time and achieves a good luminous effect. This aerosol product is provided with a container having a two-layer structure provided with a discharging mechanism for simultaneously discharging contents filled in two stock-solution filling spaces, wherein the container is characterized in that: a propellant constituted of a pressurized gas is filled in apropellant filling space; a first stock-solution filling space is filled with a first stock-solution composition which has a viscosity (at 20 DEG C) of 10,000-200,000 mPa s and contains an oxalic acidester, a luminescent substance and a thickening agent; a second stock-solution filling space is filled with a second stock-solution composition which has a viscosity (at 20 DEG C) of 10,000-200,000 mPa s and contains hydrogen peroxide, a hydrogen peroxide decomposition catalyst and a thickening agent; the discharging mechanism is provided with a mixture discharging member having a mixing means for mixing the two kinds of stock- solution compositions; and a chemiluminescent composition is formed by the two kinds of stock-solution compositions being mixed.
