The present invention has as its object the provision of a two-liquid mixing-type aerosol toothpaste that has high storage stability and can easily form a high-functional toothpaste composition.The two-liquid mixing-type aerosol toothpaste of the present invention has a double-structure container including a propellant filling space and two liquid concentrate filling spaces and having a discharging mechanism for simultaneously discharging contents filled in the two liquid concentrate filling spaces. The propellant filling space is filled with a propellant composed of a compressed gas. A first liquid concentrate filling space is filled with a first liquid concentrate composition containing an active ingredient and having a viscosity of 1,000 to 125,000 mPa·s at a temperature of 20° C. A second liquid concentrate filling space is filled with a second liquid concentrate composition free of the active ingredient and having a viscosity of 1,000 to 125,000 mPa·s at a temperature of 20° C.
