Abstract
An ionization device includes an irradiation unit to irradiate at least a region of a surface of a sample with laser light to scatter particles contained on the surface of the sample, a liquid holding unit having a distal end to hold a liquid on an outer periphery of the distal end, an extract electrode to extract ionized ions, and a voltage application unit to apply a voltage between the liquid holding unit and the extract electrode to generate the ions from the liquid held on the outer periphery of the distal end. The region and the distal end are disposed so as not to make contact with each other but to be in close proximity to each other so that the liquid held on the outer periphery of the distal end attracts particles desorbed from the sample as a result of irradiation with the laser light.
