Abstract: A target structure includes a target and a cooling portion. The target generates neutrons by being irradiated with a charged particle beam. The cooling portion includes a front surface and a back surface that face to sides opposite to each other. The target is joined directly or indirectly to the front surface. A flow path for flowing of cooling liquid including hydrogen elements is formed in the cooling portion. When viewed in a thickness direction of the cooling portion from the front surface to the back surface, the flow path is positioned off a center portion of the target.
