To provide a technique advantageous to improve the spatial resolution of a radiation imaging panel.SOLUTION: The radiation imaging panel includes a substrate, a plurality of pixels which are arranged on the first surface of the substrate, a first wavelength conversion part which includes a first scintillator arranged so as to cover the first surface, and a second wavelength conversion part which includes a second scintillator arranged so as to cover the second surface opposite to the first surface of the substrate. In orthogonal projection with respect to the first surface, the substrate has a central area including a pixel area where the plurality of pixels are arranged and a peripheral area between the outer edge of the central area and the outer edge of the substrate, the second surface has a recess so that the thickness of the substrate in the central area is thinner than that in the peripheral area, and the second wavelength conversion part is arranged in the recess.SELECTED DRAWING: Figure 1【課題】放射線撮像パネルの空間分解能の向上に有利な技術を提供する。【解決手段】基板と、基板の第1の面に配された複数の画素と、第1の面を覆うように配された第1のシンチレータを含む第1の波長変換部と、基板の第1の面とは反対側の第2の面を覆うように配された第2のシンチレータを含む第2の波長変換部と、を含み、第1の面に対する正射影において、基板は、複数の画素が配された画素領域を含む中央領域と、中央領域の外縁と基板の外縁との間の周辺領域とを含み、中央領域が周辺領域よりも基板の厚さが薄くなるように、第2の面は凹部を備え、第2の波長変換部が、凹部に配される。【選択図】図1
