Abstract: The present invention discloses a cathode ray tube including an electron gun having a heater and a method for manufacturing the same. The heater is formed using a coil and includes a heat-emitting part having a heat-focusing part on which heat generated from the coil is focused and a buffering part for buffering shocks, and a triple coil part formed such that the coil is wound in three levels at predetermined pitches. The pitches of second and third levels of the triple coil part are substantially identical to each other and larger than the pitch of the first level. The present invention can improve the quality and welding reliability of the heater and reduce the quantity of coil required and time required for winding the coil while accomplishing high efficiency heating.
