The multi-Skyrmion system with axially and reflectively symmetric configuration is examined for the SU(2) case. The soliton is quantized by the collective coordinate method. It is shown that there are bound B = 2 and B = 3 soliton solutions and that this model yields the B = 2, T = 0 and JP = 1+ soliton as the lowest physical state. Excited energies of natural-parity diproton resonances are also given. It is also shown that the Skyrmion-Skyrmion potential exhibits attraction in the inside region. The field distribution and baryon density are given in the case of zero and some finite distances between two Skyrmions.
