Abstract
In a related-art composite scintillator in which pores in a porous scintillator are filled with an absorbing member or the like, as the ratio between the structural period of the composite and the thickness in an optical waveguide direction becomes smaller, almost all light is absorbed, and, in some cases, it is difficult to obtain a sufficient light amount for forming an adequate image. Provided is a scintillator including multiple first phases having directionality in a direction connecting two surfaces thereof which are not located on same surface and a second phase positioned around the first phases, in which each of the multiple first phases is in the shape of a column, and an absorbing portion is provided in part of one of the two kinds of phases, which has a lower refractive index.
