Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an inspection method and an inspection apparatus for easily discriminating a float surface of a float glass of a glass substrate used for a plasma display panel, etc. SOLUTION: The discrimination of the float surface of the float glass is easily performed by irradiating the surfaces 2a and 2b of the float glass 2 with ultraviolet ray 1a and 1b and inspecting visual ray 4 emitted at that time from the surfaces 2a and 2b by a visual ray detector 3a and 3b.
