Abstract
The present invention assures a satisfactory adhesiveness of an input screen,of an X-ray image intensifier, high resolution of an output image and brightness uniformity as required, by configuring an aluminum or aluminum alloy substrate,so to have a concave surface with minute irregularities of the substrate material removed by burnishing, excepting gentle irregularities,without directivity which are caused by pressing. The gentle irregularities,of the substrate,preferably have an average length L in a range of 50 &mgr;m to 300 &mgr;m between the neighboring bottoms and an average height H in a range of 0.3 &mgr;m to 4.0 &mgr;m from peaks to bottoms. The invention improves resolution with light on the substrate surface suppressed from being scattered, and decreases image noises which are caused by the minute irregularities.
