An image pickup tube characterized in that it is electrically short-circuited to the mesh electrode terminal. (2) Constructed so that the capacitance between the mesh electrode and the electrostatic deflection electrode is more than twice that of the case without this conductor layer due to the conductor layer wrapped around the outer periphery of the vacuum envelope. An image pickup tube according to claim 1, which is obtained by registering a utility model. (3) The image pickup tube according to claim 1, wherein the conductor layer is made of metal foil or thin metal plate. (4) The conductor layer is comprised of a vapor-deposited or coated metal film.
