Abstract: The present disclosure relates to a radiation detector that is capable of preventing deterioration in an SN ratio of a read-out signal. The radiation detector includes a TlBr crystalline body, and a first electrode and a second electrode that have been provided on respective electrode formation surfaces. At least one of the first electrode and the second electrode includes a first layer and a second layer. The first layer formed on the electrode formation surface contains metallic thallium, or a first alloy of metallic thallium and another metal. The second layer on the first layer contains an alloy of a first metal and a second metal. A diffusion coefficient of metallic thallium to a layer comprised of the alloy of the first metal and the second metal is smaller than a diffusion coefficient of metallic thallium to a layer comprised of the second metal.
