The purpose of the present invention is to provide a two liquid mixing type aerosol product having excellent storage stability and being capable of easily forming a highly functional discharge substance having high viscosity. This two liquid mixing type aerosol product is characterized by: comprising a double structure container having a propellant filling space and two starting liquid filling spaces and having provided therein a discharge mechanism for simultaneously discharging the contents of the two starting liquid filling spaces a propellant comprising compressed gas being filled into the propellant filling space a first starting liquid composition being filled into the first starting liquid filling space a second starting liquid composition being filled into the second starting liquid filling space and the first starting liquid composition and the second starting liquid composition having different characteristics but both having a viscosity of 1 000 125 000 mPa·s at 20°C.
