To provide a wavelength conversion member and a production method thereof.SOLUTION: The wavelength conversion member is provided that includes: a phosphor including at least one kind selected from a nitride-based phosphor and an oxynitride-based phosphor; and aluminate including at least one kind selected from the group consisting of a rare earth aluminate and an alkaline earth metal aluminate. Furthermore, the production method of a wavelength conversion member is provided that comprises: preparing a molded body obtained by mixing the phosphor including at least one kind selected from the nitride-based phosphor and the oxynitride-based phosphor and an aluminate containing at least one kind selected from the group consisting of the rare earth aluminate and the alkaline earth metal aluminate; and firing the molded body, thus the wavelength conversion member including the phosphor and the aluminate is obtained.SELECTED DRAWING: Figure 1 【課題】波長変換部材及びその製造方法を提供する。【解決手段】窒化物系蛍光体及び酸窒化物系蛍光体から選ばれる少なくとも１種を含む蛍光体と、希土類アルミン酸塩及びアルカリ土類金属アルミン酸塩からなる群から選ばれる少なくとも１種を含むアルミン酸塩とを含む波長変換部材である。また、窒化物系蛍光体及び酸窒化物系蛍光体から選ばれる少なくとも１種を含む蛍光体と、希土類アルミン酸塩及びアルカリ土類金属アルミン酸塩からなる群から選ばれる少なくとも１種を含むアルミン酸塩とを混合した成形体を準備することと、前記成形体を焼成して、前記蛍光体と前記アルミン酸塩を含む波長変換部材を得ることを特徴する、波長変換部材の製造方法である。【選択図】図１
