1. A radiation detector comprising:
a substrate made of an organic material;
a barrier layer formed on a main surface of the substrate and including thallium iodide as a main component;
a scintillator layer formed on the barrier layer and constituted of a plurality of columnar crystals including cesium iodide with thallium added thereto as a main component;
a sensor panel including a photo-detection surface provided with a photoelectric conversion element receiving light generated in the scintillator layer; and
a fiber optical plate disposed between the scintillator layer and the sensor panel, and configured to optically connect the scintillator layer and the sensor panel.
