The present invention has as its object the provision of a two-liquid mixing-type aerosol product having high formulation stability, being capable of easily forming a discharge material having a desired composition, and providing comfort during use when it is applied to the human body. A two-liquid mixing-type aerosol product 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 the 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 having a viscosity of 1 to 1000 mPa·s at a temperature of 20°C. A second liquid concentrate filling space is filled with a second liquid concentrate composition having a viscosity of 1 to 1000 mPa·s at a temperature of 20°C. The discharging mechanism has a function for breaking the first liquid concentrate composition and the second liquid concentrate composition down into fine droplets and discharging these liquid concentrate compositions as mists.
