Abstract
Provided are a charged particle beam generator and a charged particle beam device that can improve insulation reliability as a result of reducing the high electric field generated around a connection section for a conductor. The charged particle beam generatorhas: a plugthat guides high voltage from outside to a charged particle source that is in a vacuum; and a sockethaving the charged particle source attached thereto. An electric field reduction ringthat electrically connects to one of a plurality of conductors that guide high voltage is embedded inside the tip of the plug. The plurality of conductors that guide the high voltage are arranged so as to penetrate the electric field reduction ring
