Abstract
A radiographic image detector includes a scintillator panel including a substrate, and on a substrate surface of the substrate, a vapor deposition film layer in which a phosphor component is vapor-deposited in a film form together with an activator component. A vapor deposition film thickness corresponding to a thickness of the vapor deposition film layer from the substrate surface is set to a thickness within ±10% with respect to a film thickness median value over an entire surface of the vapor deposition film layer. A film thickness distribution related to the vapor deposition film thickness and an activator concentration distribution related to an activator concentration of the activator component in the vapor deposition film layer correlate with each other.
