Abstract: A radiation detector includes: a phosphor panel including a phosphor excited by entered radiation to emit fluorescence; a light receiving element that photoelectrically converts the fluorescence emitted by the phosphor; and a wiring board provided with the light receiving element, wherein the light receiving element includes a light receiving surface provided with a light receiving portion and an electrode, the phosphor panel and the light receiving element are arranged to face each other, and a surface of the phosphor panel facing the light receiving element and the light receiving surface of the light receiving element are inclined with respect to each other such that a distance between the light receiving portion and the phosphor panel is smaller than a distance between the electrode and the phosphor panel.
