PROBLEM TO BE SOLVED: To provide a method of forming a multilayer coating film having an excellent finishing property. SOLUTION: In the method of forming the multilayer coating film, a substrate is coated by a 3 coat 1 bake method using a first water-based color coating, a second water-based color coating, and a clear coating. The first water-based color coating is applied, and the coating film is predried to adjust the viscosity of the coating film to≥1×10<SP>6</SP>mPa sec (at 20°C and a shear rate of 0.1 sec<SP>-1</SP>). Subsequently the second water-based color coating is applied, and after reducing the moisture content of the second water-based color coating to 10 wt% by preheating or air blowing, the clear coating is applied.
