    摘要: A transmissive-type target for an X-ray generation tube includes a target layer (22), and a transmissive substrate (21) configured to support the target layer (22). The transmissive substrate (21) has a pair of first and second surfaces (24, 25) facing each other, and is formed of polycrystalline diamond. In the transmissive substrate (21), the first surface (24) includes polycrystalline diamond having a first average crystal grain diameter which is smaller than a second average crystal grain diameter of polycrystalline diamond included on the second surface (25) opposing thereto. The target layer (22) is supported by the first surface (24).
