Abstract: A method for manufacturing a wavelength conversion member includes: forming a phosphor layer on a base body including phosphor particles and oxide particles affixed to surfaces of the phosphor particles; and forming a cover layer covering the surfaces of the phosphor particles and surfaces of the oxide particles continuously, and having a same oxide material as the oxide particles. A wavelength conversion member includes: a base body, a phosphor layer disposed on the base body and including phosphor particles and oxide particles affixed to surfaces of the phosphor particles; and a cover layer covering the surfaces of the phosphor particles and surfaces of the oxide particles continuously, and including a same oxide material as the oxide particles.

Abstract: A wavelength converting member includes at least a first, second, and third regions, circumferentially on a disc-shaped light-transmissive substrate. The first region includes, from a light incident direction, a first and second phosphor layers. The first phosphor layer includes a first phosphor to absorb at least part of incident light and to emit a first light having a wavelength different from the incident light. The first phosphor layer defines an indentation in a surface on the second phosphor layer side, with a depth a half or more of the thickness of a portion of the first phosphor layer absent of the indentation. The second phosphor layer includes a second phosphor to absorb at least part of the first light emitted by the first phosphor and to emit a second light having a wavelength different from the first light, and is disposed in the indentation of the first phosphor layer.
