PROBLEM TO BE SOLVED: To provide a microscope illumination apparatus configured so that the loss of the amount of light is kept to a minimum and the light can be efficiently supplied to the microscope body, even in the case of light to be emitted, in particular, from any of at least three kinds of light sources, each of a different emission wavelength region and a different figure and size of the light emitting section, including a light source using an ultraviolet wavelength region as the emission wavelength. SOLUTION: The microscope illumination apparatus includes: at least three kinds of light sources 21 to 24, each of a different emission wavelength region and a different figure and size of the light-emitting section; collimator lenses 25 to 28; a means 29 introducing light emitted from the collimator lenses into a common optical path; an imaging lens 30 placed on the common optical path; and an optical fiber 31 placed so that the entrance end face 31a of the optical fiber is located at a position where the images of the individual light sources are formed through the imaging lens. The collimator lenses are constructed to have different optical properties so that an angle of incidence of light on the optical fiber through the imaging lens may become smaller than a critical angle of the optical fiber and each of images of the light sources formed through the imaging lens has the maximum size to such an extent that the image is not larger than the entrance end face of the optical fiber.
