Abstract
A radiation imaging panel comprising a substrate in which a plurality of pixels each including a photoelectric conversion element are arranged, a scintillator containing a plurality of columnar crystals arranged on the substrate, and a protective layer is provided. The protective layer includes a first resin layer arranged so as to cover the scintillator and a second resin layer arranged on the first resin layer, and the first resin layer contains a resin to which particles of a metal compound is added. A light reflectance r1 [%] of the first resin layer satisfies 47%<r1<75%, and a light reflectance r2 [%] of the second resin layer and a light absorptance a2 [%] of the second resin layer satisfy r2<a2.
