摘要： 本發明提供一種光提取效率高且發光強度優異之波長轉換構件、及使用其之發光裝置。 本發明之波長轉換構件之特徵在於：其係含有螢光體之板狀之波長轉換構件1，且 具有光入射面1a、及與光入射面1a為相反側之光出射面1b， 於將光入射面1a之表面粗糙度設為Rain，將光出射面1b之表面粗糙度設為Raout之情形時，Rain為0.01～0.05 µm，且Raout-Rain為0.01～0.2 µm。 | The present invention provides a wavelength converting member having high light extraction efficiency and excellent light emission intensity, and a light emitting device using the same. The wavelength-converting member according to the present invention is characterized in that it is a plate-like wavelength-converting member 1 containing a fluorescent body, and has a light entrance face 1 a, and a light exit face 1 b on the opposite side from the light entrance face 1 a, and the light exit face 1 b is formed on the opposite side of the light entrance face 1 a. In the case where the surface roughness of the light incident surface 1 a is set to Rain, and the surface roughness of the light exiting surface 1 b is set to Raout, Rain is 0.01 to 0.05 pm, and Raout-Rain is 0.01 to 0.2 pm.
