摘要

PROBLEM TO BE SOLVED: To provide an ionization device capable of increasing ion density at ionizing sample molecules using soft X-rays.

SOLUTION: The ionization device 1 comprises a main body part 21, a soft X-ray tube 3, and electrodes 4, 5. The main body part 21 extends in a prescribed axial direction and has an ionization chamber 2 to ionize the sample molecules, an inlet port 22 to introduce the sample molecules into the ionization chamber 2, and an exhaust port 23 to exhaust the sample molecule ions. The soft X-ray tube 3 has an electron source 31 and a target part 32 to generate soft X-rays by receiving electrons from the electron source 31. The electrodes 4, 5 are respectively installed on one end side and the other end side of the ionization chamber 2. The soft X-ray outgoing axial direction of the soft X-ray tube 3 crosses the above prescribed axial direction. An electrode 32b provided in the target part 32 and the electrode 5 are mutually short-circuited. The center axis direction of the inlet port 22 crosses the soft X-ray outgoing axial direction.
