The vortex phase and the nature of the double transition field based on two-component Ginzburg-Landau theory in the magnetic field was investigated. It was observed that the vortex lattice deformed from 60° triangular lattice caused by the towfold-symmetric second order parameter. In the two-component superconductor, a possibility of the vortex sheet structure was discussed. It was found that these characters were important to identify the multiple superconducting phase in the superconductor PrOs4Sb12.
