Claim Text:
1. A fluorescence detection method for detecting plural types of fluorescence emitted from two or more kinds of fluorescent molecules, comprising: subjecting each of the two or more kinds of fluorescent molecules to multi-photon excitation by exciting light having an exciting wavelength equal to or shorter than 525 nm in a visible region so that each of the two or more kinds of fluorescent molecules is raised to a second excited level higher than a first excited level and then returns to a ground level to generate fluorescence upon making use of an absorption wavelength band in a deep ultraviolet region of each of the two or more kinds of fluorescent molecules; and simultaneously detecting plural types of fluorescence generated on a shorter-wavelength side or on both of the shorter-wavelength side and a longer-wavelength side of the exciting wavelength of the exciting light.
