An x-ray generation device and a cathode thereof are provided. The x-ray generation device comprises the cathode, a focusing device, an anode target, and a glass container. The cathode comprises a container and an electron beam generator. The container has a base and a side wall surrounding the base, and both of them define a trench. The electron beam generator comprises at least one metal unit, each of the at least one metal unit is chemical-vapor-deposited a carbon layer, and each of the at least one metal unit is disposed on a bottom of the trench. The at least one metal unit is electrically connected to an outer metal unit of the x-ray generation device. The glass container contains the cathode, the focusing device, and the anode target in sequence. Each of the at least one carbon layer faces the anode target. The glass container has a valve for evacuating and a window for emitting an x-ray. |
