Zusammenfassung:Provided is a wavelength conversion member exhibiting high reliability. Wavelength conversion member (100) of the present disclosure includes phosphor layer (20) having matrix (21) containing ZnO and phosphor particles (22) embedded in matrix (21) and first protective layer (30) that contains at least one selected from the group consisting of ZnCl2, ZnS and ZnSO4and covers phosphor layer (20). For example, first protective layer (30) is in contact with phosphor layer (20). For example, ZnO is c-axis-oriented polycrystalline ZnO.
