X-ray generator of the present invention, the electron passage 8; Having a target (9c) provided on the substrate (9a), and to emit electrons passed through the electron passage 8 to the target (9c) generates X-rays (11a), the target (9c) has a substrate (9a) and a is in the center region; At least a portion of the peripheral area of the target (9c) a substrate (9a) that is not covered with is the one reflected from a target electronic (5b) with respect to the X-rays (11b) generated when incident on the inner wall of the electron passage 8 and it has a high transmittance than the center region of the substrate (9a) covered by the target (9c). By using the electron reflected from the target (9c) effectively, it is possible to improve the X-ray generation efficiency.
