PROBLEM TO BE SOLVED: To provide a phosphor by an oxide solid solution having high emission intensity and a superstructure using a solid phase reaction or sol gel reaction which is a general ceramic manufacturing method. SOLUTION: The wavelength conversion phosphor absorbs at least one of near ultra-violet ray, blue light and green light and emits red light by the oxide solid solution forming the superstructure represented by Li<SB>1+x-y</SB>Nb<SB>1-x-3y</SB>Ti<SB>x+4y</SB>O<SB>3</SB>represented as the expression 1 (wherein x and y meet 0.04≤x≤0.333 and 0≤y≤0.09) and the oxide solid solution of a powder or bulk body or thin film activated with europium and is represented by Li<SB>1+x-y</SB>Nb<SB>1-x-3y</SB>Ti<SB>x+4y</SB>O<SB>3</SB>:Eu represented as the expression 2 (wherein x and y meet 0.04≤x≤0.333 and 0≤y≤0.09; and an amount of added Eu<SB>2</SB>O<SB>3</SB>is 0.5-3.0 wt.%) manufactured by the general ceramic manufacturing method.
