Abstract: A radiation detector includes: an elongated wavelength conversion member that emits fluorescent light according to incident radiation; a photoelectric conversion element that receives the fluorescent light emitted from the wavelength conversion member, and generates an electrical signal; and a light condenser that is disposed between the wavelength conversion member and the photoelectric conversion element, and focuses the fluorescent light emitted from the wavelength conversion member on the photoelectric conversion element. The optical axis of the radiation incident on the wavelength conversion member and the optical axis of the light condenser extend in directions different from each other in view of the longitudinal direction of the wavelength conversion member. One focal point of the light condenser is disposed at the wavelength conversion member. The other focal point is disposed at the photoelectric conversion element.

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.

Abstract: An electromagnetic wave detector is provided. The electromagnetic wave detector comprises: a base; a sensor element arranged on a principal surface of the base and configured to convert, into an electrical signal, light emitted from a scintillator which receives an electromagnetic wave; a lens portion arranged between the scintillator and the sensor element and configured to collect the light generated by the scintillator to the sensor element; a light transmissive portion arranged between the lens portion and the sensor element and configured to transmit the light generated by the scintillator; and a shielding portion including an inner wall located on a periphery of the sensor element and configured to shield the electromagnetic wave. The inner wall is arranged between the light transmissive portion and the principal surface.
