Abstract
A ceramic scintillator array of an embodiment includes: a plurality of scintillator segments each composed of a sintered compact of a rare earth oxysulfide phosphor; and a reflective layer interposed between the scintillator segments adjacent to each other. The reflective layer contains a transparent resin and reflective particles dispersed in the transparent resin. The reflective particles contain titanium oxide and at least one inorganic substance selected from the group consisting of alumina, zirconia, and silica. A glass transition point of the transparent resin is 50° C. or higher, and a thermal expansion coefficient of the transparent resin at a temperature higher than the glass transition point is 3.5×10/° C. or less.
