| 摘要 |
The present invention provides an X-ray detecting element that obtains radiation images by X-rays of different energies by irradiation of X-rays at a single time, without positional offset arising. Two X-ray detecting sections are provided so as to be layered at a substrate in a direction of irradiation of X-rays. A first X-ray detecting section detects irradiated X-rays, and a second X-ray detecting section detects X-rays that are transmitted through the first X-ray detecting section.
