A spontaneous breaking of conformal supersymmetry is shown to be induced in the massless Wess-Zumino model by 0(2,3)-invariant classical solutions of the equations of motion. The corresponding little group is the graded subgroup OSp/sup I/(1,4) of the conformal supergroup. The symmetry with respect to another OSp(1,4) subgroup (OSp/sup I/I(1,4)) is spontaneously broken to the O(2,3) symmetry and a massive Goldstone fermion makes its appearance. Using a superfield Weyl transformation we reduce the theory to an explicitly OSp(1,4) invariant form in which its spontaneously broken phase admits a standard model interpretation. An OSp(1,4) analog of the massive Wess-Zumino model is constructed and its vacuum structure is investigated. Spontaneous breaking of the P and CP parities is obtained.
