It is shown that chiral symmetry is spontaneously broken by a constant magnetic field in QED. The dynamical mass of fermions (energy gap in the fermion spectrum) is mdyn{}C {}eB exp[-({π}/{α})1/2], where B is the magnetic field, the constant C is of order one, and {α}=e²/4{π} is the renormalized coupling constant. Possible applications of this effect are discussed.
