Abstract: A plasma generating method, used in a plasma generating apparatus which includes a container, a first electrode, and a second electrode, includes: supplying a liquid in the container so that the second electrode is in contact with the liquid; in a first period, generating first plasma in a bubble generated in the liquid by applying a first voltage between the first electrode and the second electrode; supplying a first gas in the liquid in a second period after the first period; and generating second plasma in the first gas by applying a second voltage between the first electrode and the second electrode. In generating the first plasma, the first gas is not supplied in the liquid. The bubble contains a second gas.

Abstract: A liquid processing apparatus includes a container for holding liquid, a first electrode, a second electrode, a first insulator that has a cylindrical shape and at least partly surrounds a side face of the first electrode via a space, the first insulator having an opening in an end face of the first insulator, a gas supply device that supplies gas into the space and releases the gas into the liquid via the opening, a power source that applies a voltage between the first electrode and the second electrode and generates plasma, and a metallic member that partly surrounds the side face of the first electrode via the space. The metallic member is electrically connected to the first electrode. At least a part of the first insulator is disposed between the first electrode and the metallic member.
