Abstract
An X-ray detector (5) comprises an X-ray-electric charge conversion film (21) for directly converting into charges an incident X-ray that has passed through a subject (2) and is received, and a charge information reading section (15) for detecting charges produced by the X-ray-electric charge conversion film (21) as image signals. The X-ray-electric charge conversion film (21) consists essentially of a rare-earth compound containing at least one of rare-earth element and at least one of element selected from oxygen, sulfur, selenium and tellurium. The X-ray-electric charge conversion film (21) does not adversely affect human bodies and environment, and is excellent in sensitivity, film-forming feature and the like. Accordingly, the X-ray detector (5) which is provided with the improved X-ray detection sensitivity, detection accuracy and the like with environmental loads and the like decreased can be provided.
