The formulation of SU(3) Skyrme model is developed with the collective coordinate method. Quantization of them is done with the method of canonical commutation relations. SU(3) Euler angles are introduced for separation of variables and the symmetry breaking mass term is shown to depend on one variable only. The eigenequations are solved explicitly with these Euler angles. Static properties of baryons are calculated with this method. Baryon masses are well reproduced with the small value of the pion decay constant. Magnetic moment and charge radius are reproduced qualitatively with the present parameter fit. The effects of the SU(3) symmetry breaking are discussed. The strong symmetry breaking limit of the present formulation is discussed and it is shown that the model becomes the SU(2) one in this limit. The relation with the bound state approach is discussed based on this limit.
