<P>PROBLEM TO BE SOLVED: To solve the problem wherein an antibacterial agent does not so much deposit on the surface and the antibacterial property is weak because, if silicone oil and inorganic antibact erial agents are mixed by kneading simultaneously, silicone oil is oriented at the surface of a resin preferentially to the antibacterial agent. Ž<P>SOLUTION: The polypropylene resin 1 comprises a silicone oil 3 and an antibacterial agent 4, and the antibacterial agent 4 is the one supporting or containing at least silver or zinc ion on the surface of an inorganic material having hydroxyl group, and realizes a polypropylene resin 1 having stain-resistance and antibacterial property by substituting at least one part or all part of the hydroxyl group by a hydrophobic group, because the antibacterial agent 4 orients on the surface of the polypropylene resin without being buried in the silicone oil 3 and can exhibit antibacterial property.
