Abstract
When a heating process is performed in a state where a thermal transfer sheet is superimposed on a scintillator plate, a film of the thermal transfer sheet is separated from the thermal transfer sheet and adhered onto the scintillator plate. The film includes a protective layer, an aluminum layer, and an adhesive layer. The aluminum layer is protected by the protective layer. Because the scintillator plate by itself functions as a rear surface support substrate with respect to the protective layer and the aluminum layer, a film which is highly resistive against an external effect can be formed. A plurality of films can be layered on the scintillator plate. A pressure transfer method can also be used for formation of the film. A scintillator member in which the film has been formed is disposed in a radiation measuring device.
