Abstract
A fluorescent light source device includes a wavelength conversion member formed of a phosphor to be excited by excitation light. The wavelength conversion member includes a fluorescent member containing the phosphor, and a photonic structure part formed on the fluorescent member. An upper surface of the photonic structure part serves as a fluorescent light emitting surface of the wavelength conversion member. The photonic structure part is made from an inorganic compound layer that may be formed of a metal oxide and has a columnar structure extending in a direction away from the fluorescent member.
