    • The present invention relates to a curved-surface detector that is bent to have a curved surface so as to capture a radiographic image. A method for manufacturing a curved-surface detector according to an embodiment of the present invention provides a method for manufacturing a curved-surface detector in which a detector for converting radiation into an electrical signal so as to obtain a radiographic image is bent in such a manner as to have a curved surface. The method comprises the steps of: slimming a sensor substrate having photoelectric elements arranged thereon so as to achieve a predetermined thickness; bending the sensor substrate that is slimmed to the predetermined thickness to have a curved-surface by placing the same in a jig that is curved in such a manner as to have a curved surface; and bonding a flexible scintillator substrate that is struck by the radiation and illuminated to an upper surface of the sensor substrate so that the sensor substrate that is bent to have a curved-surface by means of the jig to maintain its curved surface, wherein the scintillator substrate is bonded to a bonded layer while being curved with the same curvature as the curvature of the sensor substrate, and maintains the curvature of the sensor substrate in order to prevent detachment or deformation of a bonded part between the scintillator substrate and the sensor substrate. As a result, a radiographic image in which distortion is minimised can be obtained by manufacturing the curved-surface detector that is bent to have a curved surface.
