Z-boson decay $Z \rightarrow f\tilde{f}\gamma\gamma$ in the Standard Model isanalysed. The distribution function on the invariant masses of the photon andfermion pairs is calculated in the leading logarithmic approximation. It isshown that this distribution function has a specific shape of a ``crest''.
