An objective of the present invention is to provide a portable X-ray generator capable of significantly reducing the weight of a high-pressure generating tube since the high-pressure generating tube is configured to prevent radiation leakage with shielding lead. The portable X-ray generator comprises a first shielding member, a solid insulated member, and second and third shielding members.본 발명은 휴대용 X-ray 발생장치에 관한 것으로, 고압 발생 튜브만을 차폐용 납으로 방사선 누설을 방지하도록 구성하므로, 그 무게를 현저히 감소시킬 수 있는 X-ray 발생장치를 제공하는데 그 목적이 있다.
