A stimulable phosphor layer composed of a plurality of stimulable phosphor sublayers overlaid one upon another is overlaid upon a substrate. At least two adjacent stimulable phosphor sublayers are overlaid one upon the other such that a temporary substrate contact side surface of one of the two adjacent stimulable phosphor sublayers, which surface was in contact with a temporary substrate utilized when the one adjacent stimulable phosphor sublayer was formed, and a temporary substrate contact side surface of the other adjacent stimulable phosphor sublayer, which surface was in contact with a temporary substrate, stand facing each other. A top stimulable phosphor sublayer contains a polyurethane binder, which has a weight-average molecular weight falling within the range of 200,000 to 500,000, in a proportion falling within the range of 20% by weight to 90% by weight with respect to the total binder contained in the top stimulable phosphor sublayer.
