    Abstract: A color conversion element includes: a substrate; a phosphor portion that is disposed above the substrate, receives laser light transmitted from an outside, and emits light in a color different from a color of the laser light; a reflective layer that includes a dielectric multilayer film and is disposed on a principal surface of the phosphor portion facing the substrate; and a joining portion interposed between the reflective layer and the substrate to join the reflective layer and the substrate. The joining portion includes an air layer that exposes the reflective layer in a position where the air layer at least partially overlaps an irradiation region in a plan view, the irradiation region being a region irradiated with the laser light on the phosphor portion.

    Abstract: Light emitting device includes structure protruding from a side of a surface of second conductive semiconductor layer of LED chip toward a side of a surface of second conductor portion of mounting substrate to contact the surface of second conductor portion, and is positioned to extend around an outer periphery of second electrode. First electrode and a first conductor portion are joined to each other by first joint portion, and second joint portion joining second electrode and second conductor portion to each other fills a space surrounded by second electrode, protruding structure, and second conductor portion. Protruding structure is disposed to extend around the outer periphery of second electrode to surround second joint portion in planar view. A part of mounting substrate overlapping protruding structure in planar view is either identical in height to or lower than a part of second conductor portion joined to second joint portion.
