<p>An X-ray light emitting phosphor film (22) such as a CsI film for converting X-ray into light is formed on an input substrate (21) constituting the input unit of an X-ray image detector. A high energy light having a wavelength of up to 500 nm is applied onto the front surface of the X-ray light emitting phosphor film (22). The front surface of the phosphor film (22) is locally sublimated and/or fused to be flattened by the high energy light irradiation. A high energy light such as a laser beam is used to be able to efficiently and homogeneously flatten the front surface of the phosphor film.</p> |
