We investigate symmetry of pairing correlation in vortex lattice state, and explain the electronic structure in this state in terms of pairing symmetry. We find that only odd-frequency pairing is present at the core centers, while at the midpoint of the vortex lines, only even-frequency pairing exists. Thus, the odd- and even-frequency pairings also form the lattice in the vortex lattice state.
