Abstract
The gauge invariant method for calculation of the effective action of the local composite fields in QFT is proposed. The effective action of the local composite fields in QED is studied up to 2-loop level. The graph rules for the local composite fields are derived. On the basis of these rules the problem of one-particle irreducibility is discussed.
