Summary:To solve the problem in which: in a scintillator plate using columnar crystals, the resolution of the scintillator plate is reduced due to scattering of light between the columnar crystals.SOLUTION: A ground of a scintillator plate in which columnar crystals are formed has a layer in which a main phase composed of a material of the columnar crystals and an auxiliary phase composed of a material different from that of the main phase cause phase separation, and thereby a scintillator is achieved which improves separation of the columnar crystals from each other to prevent scattering of light and has high resolution.SELECTED DRAWING: Figure 6 【課題】柱状結晶を用いたシンチレータプレートにおいて、柱状結晶間の光散乱により、シンチレータプレートの分解能が低下する。【解決手段】シンチレータプレートの柱状結晶を形成する下地に、柱状結晶の材料による主相と、主相とは異なる材料による副相が相分離した層を有することで、柱状結晶同士の分離を向上して光散乱を抑制し、高い分解能を有するシンチレータを実現する。【選択図】図６
