Abstract
An adiological image detection apparatus 3 includes a phosphor 60 that contains a fluorescent material which emits fluorescence by radiation exposure, and a sensor panel 61 which is provided to be in close contact with the phosphor, and detects the fluorescence emitted from the phosphor. The phosphor includes a columnar section that is formed by a group of columnar crystals 82 formed by growing crystals of the fluorescent material in a columnar shape, a radiation incident plane is provided in the sensor panel at a side opposite to the phosphor, and the sensor panel has flexibility and is curved to locate a curvature center at the radiation incident plane side.
