• Besides usual flux lines the topology of the "real" vector phase in a multicomponent superconductor admits an existence of half-quantum vortices in the bulk. These vortices have a divergent energy near H_<c1>. However, the possibility of their existence reveals itself in an instability of a usual singular one-quantum vortex towards dissociation into the nonsingular bound pair of half-quantum vortices. Considering an example of the multicomponent Ginzburg-Landau functional we found analytically critical values of phenomenological parameters corresponding to this instability, as well as the symmetry group of the vortex pair.
