Patent Number: 
Section: abstract

A scintillator panel for converting radiation into scintillation light, includes a substrate having a front surface and a back surface, a plurality of scintillator sections formed on the front surface of the substrate so as to be separate from one another, and having upper surfaces and side surfaces extending from the upper surfaces toward the front surface of the substrate, solvent permeation blocking film formed on the upper surfaces and the side surfaces of the scintillator sections so as to cover the upper surfaces and the side surfaces of the scintillator sections, and a light shielding layer formed on the solvent permeation blocking film, that is for shielding the scintillation light, and the scintillator section is composed of a plurality of columnar crystals of a scintillator material, the solvent permeation blocking film is formed so as not to fill gaps between the side surfaces of the adjacent scintillator sections.
