Ein Wellenlängen-Umwandlungs-Element enthält ein Substrat, ein dichroitische Spiegel-Schicht, eine SiO2-Schicht, eine ZnO-Schicht und eine Leuchtstoff-Schicht, welche nacheinander auf dem Substrat gestapelt sind. Die dichroitische Spiegel-Schicht reflektiert zumindest einen Teil des von oben einfallenden Lichts. Die Leuchtstoff-Schicht enthält eine Mehrzahl von Leuchtstoffen und ZnO zwischen den Leuchtstoffen. 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.
