The intraoral inspection apparatus comprises: a light source unit (11) which is provided with color-producing light sources (14) capable of inducing fluorescent lights from diseased sites by irradiating an oral cavity a wavelength adjusting device (16) which is provided with a first filter (19) that transmits, among the fluorescent lights, a light having a wavelength of a fluorescent light from a predetermined diseased site and blocks or attenuates a light having a wavelength other than this wavelength, and provided with a second filter (20) that transmits, among the fluorescent lights, a light having a wavelength of a fluorescent light from a diseased site different from the predetermined diseased site and blocks or attenuates a light having a wavelength other than this wavelength and an imaging device (21) which receives the fluorescent light transmitted through the first filter and the fluorescent light transmitted through the second filter, and converts them into electrical signals.1/3 Fig. 1 10 11 21 12 16 15 13 13 14 12a 22
