Abstract: A spray ionization device comprising: a first pipe body that has a first flow path which allows a liquid to flow therethrough, and has, at one end thereof, a first outlet through which the liquid is sprayed out; a second pipe body that surrounds the first pipe body; and a third pipe body that surrounds the second pipe body with a space interposed therebetween, that has a second flow path allowing a gas to flow therethrough, and that has a second outlet at the one end. At least the leading end part of the third pipe body including the second outlet is made of an electrically conductive material so as to serve as an electrode. Charged droplets can be sprayed from the second outlet by applying an electric field to droplets sprayed from the first outlet using a power supply connected to the electrode.

Abstract: A voltage application device includes a voltage application circuit. The voltage application circuit applies application voltage between discharge electrode and counter electrode which face each other with a clearance left from each other to generate a discharge. The voltage application device forms discharge path partially and dielectrically broken between discharge electrode and counter electrode when a discharge is generated. Discharge path includes first dielectric breakdown region formed around discharge electrode, and second dielectric breakdown region formed around counter electrode.
