Abstract: A light source device is provided. The light source device includes: a ferrule which holds an optical fiber; a light-emitting element which emits laser light; and a casing which houses the ferrule and the light-emitting element such that the laser light enters the optical fiber. The casing includes a through hole from a first end face to a second end face. The through hole includes a diameter which decreases in a stepwise manner from the first end face toward the second end face. The ferrule is fitted to a small bore portion of the through hole, which is smallest in diameter. The light-emitting element is fitted to a large bore portion of the through hole, which is larger in diameter than the small bore portion.

Abstract: A lighting apparatus that wavelength-converts laser light guided by an optical fiber to output light having a different wavelength as the laser light, includes: a holder that holds the optical fiber; a wavelength converter that wavelength-converts the laser light emitted from the optical fiber; and a case that holds the wavelength converter and houses the holder. The holder includes a straight groove into which one end of the optical fiber is fitted.

Abstract: A wavelength conversion member includes a substrate, a dichroic mirror layer, an SiO2 layer, a ZnO layer, and a phosphor layer, which are sequentially stacked from the substrate. The dichroic mirror layer reflects at least part of light incident from the above. The phosphor layer includes a plurality of phosphors and ZnO between the phosphors.
