PROBLEM TO BE SOLVED: To provide an ion source used in a mass spectroscometer system, capable of obtaining excellent spectrum stability and sensitivity of the apparatus as a whole. SOLUTION: The ion source consists of (a) an ionization device for generating ions and sending them to ionization region, (b) a collecting conduit adjacent to the ionization device for collecting ions generated by the ionization device, (c) a first gas source supplying gas for desolvation of the ions generated by the ionization device, and (d) a second gas source supplying gas to the ionization region at a given flow velocity.
