A battery-powered x-ray imaging apparatus uses a battery with a reduced capacity as a power source. The x-ray imaging apparatus includes a DC-AC converting part for converting a direct current of a battery to an alternating current, a high-voltage transformer for increasing a magnitude of the alternating current to output a high-voltage alternating current, an AC-DC converting part for converting the high-voltage alternating current to a high-voltage direct current, and an x-ray tube having an anode terminal and a cathode terminal electrically connected to the AC-DC converting part. The x-ray tube is designed to generate x-rays by allowing electrons emitted from the cathode terminal to impinge on the anode terminal. The DC-AC converting part, the high-voltage transformer, the AC-DC converting part and the x-ray tube are sealingly received within the housing part filled with oil.
