Provided is a radiation detecting device, which includes: a radiation detector placed to detect radiation; an electric circuit substrate formed to control the radiation detector; a cooling unit placed to cool the radiation detector and the electric circuit substrate; and a casing placed to store the radiation detector, the electric circuit substrate, and the cooling unit inside. At least an outer surface of the casing includes: a recessed part recessed across a back surface part opposite to in which the radiation enters and a lateral surface part adjacent to the rear surface part. The recessed part includes withdrawal parts formed inside. A wire connected to the electric circuit substrate to be detachable, and a pipe placed to allow a cooling medium to flow to the cooling unit are individually withdrawn external to the casing through the withdrawal parts. |
