Summary:To provide a wavelength conversion member in which deformation of a base material is suppressed and the uniformly converted light can be obtained, and also to provide a method for producing the same and a light emitting device.SOLUTION: A wavelength conversion member 10 includes: a base material 12 having a reflection surface 13 for reflecting light on one principal surface; and a phosphor layer 14 which is provided on the reflection surface 13 of the base material 12 and formed of phosphor particles 16 and a translucent ceramic 18. In the reflection surface 13 on which the phosphor layer 14 of the base material 12 is provided, the flatness is 0.10 mm or less.SELECTED DRAWING: Figure 2 【課題】基材の変形が抑制されており、均一な変換光を得ることができる波長変換部材、その製造方法、および発光装置を提供する。【解決手段】波長変換部材１０であって、一方の主面に光を反射する反射面１３を有する基材１２と、前記基材１２の前記反射面１３に設けられ、蛍光体粒子１６と透光性セラミックス１８とで形成された蛍光体層１４と、を備え、前記基材１２の前記蛍光体層１４が設けられた前記反射面１３は、平面度が０．１０ｍｍ以下である。【選択図】図２
