    In this paper, spontaneous quasi-neutrality breaking has been observed in a rotating plasma (plasma hole). Two-dimensional potential measurement revealed that a very high potential eφ/Te ∼ 5 is localized in the region of 1/5 of the plasma radius. Using the Poisson's equation and fast Fourier transform, we have evaluated the 2-D distribution of the degree of nonneutrality δn/n, where δn = ni - ne. It is found that δn/n is three orders of magnitude higher in the hole center than in the peripheral region and that the scale of quasi-neutrality breaking extends over 103 times the Debye length.
