Abstract: A radiation detector includes: a wavelength conversion member that includes a fluorescent layer that emits fluorescent light when radiation enters this layer; an image sensor that converts the fluorescent light emitted from the fluorescent layer into an electric signal; and a wiring board where the image sensor is provided. The image sensor is provided on the surface on the lower side of the wiring board along one long side of the wiring board. One part of the wavelength conversion member is provided to be overlapped on the image sensor while the other part extends from the one long side of the wiring board so as not to be overlapped on the image sensor and the wiring board when viewed from radiation incident direction. The wiring board is disposed inclined so that the side where the wavelength conversion member extends can be disposed upward.
