摘要:
A hot cathode includes: a hollow external conductor; a hollow internal conductor which is placed coaxially inside the external conductor; and a connection conductor which electrically connects tip end portions of the conductors. A heating current is folded back through the connection conductor to flow in opposite directions in the external conductor and the internal conductor.
