A linear theory is derived for ideal kink modes for a tokamak in which the condition {vert bar}{Delta}{ital q}{vert bar}{equivalent to}{vert bar}{ital q}---1{vert bar}{much lt}1 holds in a fairly long region (the corresponding profiles of {ital q} are flattened''). Dispersion relations are derived for kink modes for both monotonic and nonmonotonic flattened {ital q} profiles. The results derived here generalize the results derived by other investigators to the case of a pronounced flattening (small values of {vert bar}{Delta}{ital q}{vert bar}). An ideal instability can occur even with {beta}{sub {ital p}}=0. The growth rate reaches its maximum in the case in which there is no {ital q}({ital a})=1 resonant surface in the plasma.
