A novel scintillator channel separator is constructed of a metal thin film and at least two polymer sheets for sandwiching the metal thin film. The scintillator channel separator is used in a scintillator type X-ray detector employed in a third-generation, or fourth-generation X-ray CT system. This scintillator channel separator optically separates scintillation light emitted from scintillator elements from each other within a plurality of scintillator element channels of an X-ray scintillator array. The scintillator channel separator includes at least a first thin film capable of blocking transmission of the scintillation light occurring in the adjoining scintillator element channels; and first and second polymer sheets each having first and second major surfaces, and capable of reflecting the scintillation light. The first thin film is sandwiched between the first major surfaces of the first and second polymer sheets, and the second major surfaces of the first and second polymer sheets are stuck to corresponding side surfaces of the respective adjoining scintillator elements, so that the thin film and the first and second polymer sheets constitute the scintillator channel separator.
