   We consider an additional source of the relict photon generation stipulated by vacuum creation of vector W- and Z-bosons as a consequence of vacuum instability relatively of fast alteration their masses during electroweak phase transition in the early Universe. Preliminary estimation has showed that this contribution in the photon density of CMB is insignificant.
