When obtaining light emitted from a plurality of different wavelength bands through the same phosphor, the phosphor is excited only by light of a specific wavelength band, and the light of other wavelength bands excites the phosphor. Provided are a light source device, an imaging device, and an endoscope device that are capable of separately extracting light emitted from a phosphor and light in other wavelength bands without mutual interference by allowing the light to pass through without emitting light. A first light source, a second light source having an emission wavelength different from that of the first light source, and a predetermined excitation which is disposed apart from the first light source and the second light source. A fluorescent material 43 that absorbs light in the wavelength band and emits fluorescence, and the fluorescent material 43 is disposed on a common outgoing light path of the first light source 33 and the second light source 35. The emission wavelength of the first light source 33 is included in the predetermined excitation wavelength band, and the emission wavelength of the second light source 35 is not included.
