Abstract
The present invention is a charged-particle gun (EG) in which a negative electrode (1) and a positive electrode (9) are integrated and assembled in advance, and which can be stored and transported in a state in which the negative electrode and the positive electrode are integrated, wherein the negative electrode and the positive electrode are connected by a conductor (11) during storage and transportation of the charged-particle gun. It is thereby possible to prevent an electrode tip of the charged-particle gun from being damaged by electrical discharge caused by static electricity during storage and transportation.
