Miniature X-ray source comprising an insulation structure defining a cavity where an anode and a cathode are arranged, said cavity being evacuated, connecting means arranged to connect the anode and the cathode to a high voltage source in order to energise the X-ray source. The insulation structure includes a first layer and a second layer, the first layer facing the cavity and has a low gas permeability, and the second layer is arranged outside said first layer and has a high electrical break-through voltage. The electrical break-through voltage for the insulation structure is above a predetermined threshold value.
