The purpose of the present invention is to provide a two liquid mixing type aerosol product having excellent formulation stability being capable of easily forming a discharge substance having an expected composition and providing a good sensation when used applied to the body. This two liquid mixing type aerosol product comprises 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 is filled into the propellant filling space a first starting liquid composition having a viscosity of 1 1 000 mPa·s at 20°C is filled into the first starting liquid filling space and a second starting liquid composition having a viscosity of 1 1 000 mPa·s at 20°C is filled into the second starting liquid filling space. The discharge mechanism is characterized by having a function whereby the first starting liquid composition and the second starting liquid composition are divided into minute droplets and discharged as a mist.
