Provided is a gas-bubble spray member, the tip section of which is not damaged even when a high voltage is applied thereto. A gas-bubble spray member including: a core material formed from a conductive material; an outer shell section for tightly adhering to at least part of the core material and covering the core material, formed from an insulating material, and including an extending part extending beyond the tip of the core material; and a void having a gas-bubble spray port and formed between the extending part and the tip of the core material. Furthermore, the tip of the provided gas-bubble spray member avoids damage as a result of the formation of a thick section on the tip of the extended part that is thicker than the rest of the extended part.
