Abstract
Ceramic or base metal particles of a mean diameter of 0.01 to 0.5 .mu.m having thereon bactericidal metal particles of a mean diameter of 0.0001 to 0.1 .mu.m (the mean diameter of the bactericidal metal particles is smaller than the mean diameter of the ceramic or base metal particles) are effective to give a bactericidal surface of a plastic article when they are embedded on the surface under the condition that a portion of the particle is exposed over the surface of the plastic article. The above ceramic or base metal particles having the bactericidal metal particles on their surface are also effective to sterilize liquid or solid material.
