Claim Text:
1. An apparatus for producing a carbon nanomaterial, comprising: an aqueous medium tank accommodating an aqueous medium; a negative electrode at least partially immersed in the aqueous medium; a positive electrode disposed, in the aqueous medium, opposite a part of the negative electrode that is immersed in the aqueous medium at a distance therefrom; an arc discharge generating mechanism that applies a voltage to enable formation of an arc discharge generation region in a gap formed by the negative electrode and the positive electrode facing each other; an inert gas cavity forming mechanism that introduces an inactive gas into the gap from a side that is outside of the negative electrode and lateral to the gap, and optionally from a side of the negative electrode, and forms an inert gas cavity around the gap in the aqueous medium; and a mechanism that recovers the carbon nanomaterial synthesized from a carbon material preliminary arranged in the arc discharge generation region, wherein
