PROBLEM TO BE SOLVED: To provide a scintillator panel having a new structure that can exhibit each of increased emitted light quantity, reflection characteristics and adhesion to a support body which are required for a phosphor layer in a highly balanced state.SOLUTION: In the scintillator panel 10 including a phosphor 200 which is formed on a support body 101 and emits fluorescence by irradiation of X-rays, the phosphor 200 has a columnar portion 20 including a columnar crystal 20A formed by growing the crystal of a fluorescent substance in a columnar shape, and a non-columnar portion 25 which is provided between the columnar portion 20 and the support body 101 and includes a non-columnar crystal 25A, and the diameter of the non-columnar crystal 25A is smaller than that of the columnar crystal 20A.COPYRIGHT: (C)2012,JPO&INPIT【課題】蛍光体層に要求される発光量増加、反射特性、および支持体との密着性のそれぞれを高度にバランスされた状態で発揮しうる新規な構造のシンチレータパネルの提供。【解決手段】シンチレータパネル10は、支持体101上に形成されX線の照射によって蛍光を発する蛍光体200を備え、蛍光体200は、蛍光物質の結晶が柱状に成長してなる柱状結晶20Aを含む柱状部20、および柱状部20と支持体101との間に設けられかつ非柱状結晶25Aを含む非柱状部25を有し、非柱状結晶25Aの径は、柱状結晶20Aの径よりも小さい。【選択図】図4
