PROBLEM TO BE SOLVED : To provide a target for X-ray generation capable of preventing its crack or peel-off, by alleviating stress such as tensile stress generated on its surface or shearing stress generated at its joint part with a base stand. SOLUTION : A target member 4 composed of rare-earth metal is jointed to a base stand 2 constituted of copper with higher thermal conductivity than a component material of the target member 4 with the use of a brazing material 3 made by adding titanium to silver, with a ratio of a thickness t2 of the base stand 2 to a thickness t1 of the target member 4 within the range of 0.1 to 0.6.
