Abstract
One mode of the mass spectrometer according to the present invention is a mass spectrometer including an ion source configured to ionize a component contained in a sample gas, the ion source including: an ionization chamber having an ion ejection opening and forming a space substantially partitioned from an outside inside the ionization chamber; a thermal electron supply unit configured to supply thermal electrons to an inside of the ionization chamber; a magnetic field forming unit configured to form a magnetic field inside the ionization chamber such that the thermal electrons move helically; and a deflection electric field forming unit configured to form a deflection electric field deflecting ions derived from the component generated in the ionization chamber by a direct or indirect action of the thermal electrons in a direction against a force received from the magnetic field when the ions are moving toward the ion ejection opening.
