ABSTRACT:
An X-ray light emitting phosphor film (22) such as a CsI film that converts an X-ray to light is formed on an input substrate (21) constituting an input part of an X-ray image detector. A surface portion of the X-ray light emitting phosphor film (22) is irradiated with high-energy light having a wavelength of 500 nm or less. The surface portion of the X-ray light emitting phosphor film (22) is locally sublimated and/or fused to be flattened by the irradiation with the high-energy light. The use of the high-energy light such as a laser beam makes it possible to efficiently and uniformly flatten the surface portion of the X-ray light emitting phosphor film.
