A housing provided to a light source device has a sliding surface to which a first lens portion is fixed and an inclined support surface to which a second lens portion is fixed. The sliding surface is vertical to a direction of an optical axis of a semiconductor laser and wider than a first fixing surface of the first lens portion that is fixed to the sliding surface. The inclined support surface is parallel to the direction of the optical axis and wider than a second fixing surface of the second lens portion that is fixed to the inclined support surface.

Light source device and manufacturing method thereof

A wavelength conversion member that includes a single crystal phosphor and has a high yield rate is provided. A light emitting unit () is a wavelength conversion member that converts a wavelength of a laser light output from a laser light source and includes a phosphor layer () formed of a single crystal phosphor. A plane orientation of a principal plane (), which has an area larger than those of divided planes, of the phosphor layer is {111}, and a plane orientation of some divided planes out of the plurality of divided planes is {1-10}.
