A theory is developed for the stationary Josephson effect in superconductive constrictions (microbridges). The theory is based on the microscopic Eilenberger equations and is valid for arbitrary temperatures 0>a (where l is the free path length; a is the orifice radius) the current is expressed by the formula The critical current of a pure microbridge at t=0 is twice the critical current of a tunnel junction with the same normal resistance R/sub N/, and the phase-current relationship at the points Q= +- ..pi.. is discontinuous. The properties of microbridges in the pure (l>>a) and dirty (lvery-much-less-thana) limits are compared.
