Abstract：
Considered two dimensional self-dual fileds,the symplectic structure on the space of sloutions is given.It is shown that this structure is poincare invariant.The Lanrangian of two dimensional self-dual field is invariant under infinite one component conformal group,then this symplectic structure is also invariant under this conformal group.The conserved currents in geometrical formalism are also obtained.
