摘要
A rotatable anode target for an X-ray tube (1) of the present invention includes a metallic disc (2) which includes a first crystal structure; a metallic cylinder (3) which is joined with the metallic disc and includes a second crystal structure, where a first average aspect ratio of first crystal grains positioning at a first region within 2 mm from a interface between the metallic disc and the metallic cylinder is less than 2, and a second average aspect ratio of second crystal grains positioning at a second region within 2 mm from the interface is 2 or more and 8 or less. It is thereby possible to provide an X-ray tube target which has high heat release performance and where thermal deformation is difficult to occur.
