To provide a wavelength conversion member having a light reflection unit that has excellent durability and can favorably reflect primary light, and secondary light and a light source module.SOLUTION: A wavelength conversion member (20) includes a wavelength conversion unit (21) for performing wavelength conversion of primary light of a prescribed wavelength to emit secondary light and a light reflection unit (22) that is disposed adjacent to the wavelength conversion unit (21) to reflect the primary light and secondary light. The light reflection unit (22) is constituted by a composite ceramics sintering body of a SiOphase (23) and a TiOphase (24).SELECTED DRAWING: Figure 2 【課題】耐久性に優れるとともに良好に一次光と二次光を反射できる光反射部を備えた波長変換部材および光源モジュールを提供する。【解決手段】所定波長の一次光を波長変換して二次光を出射する波長変換部（２１）と、波長変換部（２１）に隣接して配置され、一次光および二次光を反射する光反射部（２２）を備え、光反射部（２２）はＳｉＯ２相（２３）とＴｉＯ２相（２４）を複合化したセラミクス焼結体で構成されている波長変換部材（２０）。【選択図】図２
