Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an aerosol composition of a one-package soft foam polyurethane excellent in workability, having good performances and excellent in hermetic properties. SOLUTION: In the aerosol composition of the one-package soft foam polyurethane which contains a polyurethane prepolymer, a propellant and other additives, the polyurethane prepolymer is the one obtained by reacting a polyol having 2-3 functional groups and a molecular weight of 1,000-10,000 with pure MDI in the condition that NCO index is 3-4.5.
