1. An x-ray radiation detector comprising:
a support table in which an attachment surface having a curved surface shape is formed;
a sensor panel which has a rectangular plate shape and is attached to the attachment surface while being curved following the curved surface shape and in which pixels that include thin film transistors and detect x-ray radiation are two-dimensionally arranged;
a circuit board;
a plurality of flexible cables that connect a curved side of the sensor panel and the circuit board, are arranged along the curved side, and are bent to dispose the circuit board at a set angle with respect to the sensor panel; and
a reduction structure that reduces a bias of a stretching force applied to the plurality of flexible cables caused by the curved side.
