Patent ID: 7294847

Claim:
A radiographic image detector comprising: a first electrode layer for transmitting electromagnetic waves carrying a radiographic image; a photoconductive recording layer for producing electric charges by being irradiated with said electromagnetic waves; a charge accumulating portion for storing said electric charge produced in said photoconductive recording layer; a photoconductive read-out layer for producing electric charges by being irradiated with image-reading light; a second electrode layer having a first stripe electrode, in which a plurality of first line electrodes for transmitting said image-reading light are arranged in parallel at predetermined intervals, and a second stripe electrode, in which a plurality of second line electrodes are arranged in parallel between said first line electrodes; and an insulating member mounted on at least one of side surfaces extending in a longitudinal direction of said second line electrode and on a part or whole of a top surface of said second line electrode continuous to said side surfaces, wherein said insulating member is formed from a material that absorbs said image-reading light; said first electrode layer, said photoconductive recording layer, said photoconductive read-out layer, and said second electrode layer being stacked in this order.
