The invention relates to an ion source. The ion source comprises a vacuum container, an ion electrode and a field emission electron source, wherein the vacuum container is provided with a gas inlet and an ion outgoing hole; the ion electrode is arranged at the ion outgoing hole of the vacuum container; the field emission electron source is arranged in the vacuum container; an electron outgoing part of the field emission electron source is formed on a cathode electrode, so that an electron emission end of an electron emitter is not exposed through the electron outgoing part; and thus, when ions produced by the collision of the electrons emitted by the electron emitter and free gas molecules in the vacuum move towards an electron extraction electrode, the ions do not bombard the electron emitter so as to prolong the life of the electron emitter.
