Patent ID: 7994490

Claim:
A radiation image converting panel comprising: a support body having a first main surface and a second main surface opposing said first main surface; and a radiation converting film provided on a film forming region which exists within said first main surface of said support body and includes at least a gravity center position of said first main surface, said radiation converting film being comprised of columnar crystals which are coindicent or tilted at a predetermined angle with respect to a normal direction of said first main surface, wherein, in the film forming region of said first main surface, a part of said radiation converting film having a maximum film thickness locates on a central area around the gravity center position whose radius equals 5% or less of a minimum distance from the gravity center position to an edge of said film forming region, and a part of said radiation converting film having a minimum film thickness locates on a middle area sandwiched by a circumference of a circle whose radius equals 80% of the minimum distance and a contour of the central area.
