Abstract
The invention provides radiographic image detectors in which a scintillator layer itself exhibits improved flexibility and is prevented from crystal breakage while the scintillator layer and a photoelectric conversion element are bonded to each other via uniform thickness without forming defects. The radiographic image detector includes a substrate, a scintillator layer with a columnar crystal structure disposed on the substrate, an optical coupling layer and a photoelectric conversion element. The scintillator layer has a flexural elastic modulus Esc satisfying relationships represented by Expression (I) as measured by a cantilever test in which the scintillator layer disposed on the substrate is held in a cantilever condition and is bent under a uniformly distributed load with the columnar crystal structure side being bent outward:≦−0.43+372 and≧−0.16+98  (I) (In Expression (I), Esc is the flexural elastic modulus (kg/mm) of the scintillator layer and M is the thickness (μm) of the scintillator layer).
