PROBLEM TO BE SOLVED: To provide an inspection method which can inspect the quality of a polyol composition without requiring skill by mixing and stirring a polyol composition and a polyisocyanate component with a stirring efficiency conforming to actual use condition. SOLUTION: In the inspection method of a polyol composition for polyurethane foam which uses at least a cylindrical reaction vessel 30, a weight measuring device 32, a mixing head 15, and a non-contact distance measuring device 34; and in which the mixing head 15 is for mixing the polyol composition sent by a pump 27 and the polyisocyanate component sent by a pump 29 and ejecting a mixture of them as a foaming raw liquid composition, the reaction vessel is placed on the weight measuring device and is for measuring the foaming raw liquid composition, the foaming raw liquid composition is injected to the reaction vessel, the change of the peak position when the foaming raw liquid composition is foamed and hardened, with the non-contact distance measuring device to produce a foaming curve for measuring the reaction speed and the density.
