This invention relates to a method of producing polymer spherical bodies and is to produce a large size spherical body having no residual strain. This method comprises suspending a liquid monomer in a supporting liquid having a magnetic susceptibility χ2 larger than a magnetic susceptibility χ1 of any one of the monomer and the resulting polymer and not dissolving substantially the monomer, and applying a gradient magnetic field to the supporting liquid to float droplets of the monomer at a given position in the supporting liquid, and polymerizing and solidifying the droplets while maintaining a state that the droplet is substantially shaped into a sphere through surface tension. This method is made possible to produce polymer spherical bodies capable of using in optical application and the like.
