There is provided a novel method of forming uniform viral particles under physiological conditions. The method of forming uniform-sized viral particle aggregates composed of viral protein is characterized by incubating a viral protein such as SV40 virus VP1 at pH 5.0 to 7.0, room temperature, in the presence of 130 mM to 170 mM sodium chloride and 1.5 mM to 2.5 mM divalent cation, and in the presence of a particle formation acceleration factor such as SV40 VP2. For encapsulation of a substance to be encapsulated in the viral particles, the substance to be encapsulated is included during the incubation.
