PROBLEM TO BE SOLVED: To provide an antibacterial composite particle capable of exhibiting sufficient antibacterial properties when blended in a resin molded product, a fiber, or the like, and to provide a process for producing the antibacterial composite particle. SOLUTION: This antibacterial composite particle comprises an antibacterial inorganic particle A having silver or a silver ion and a degree of hydrophobization of 20% or less and an antibacterial inorganic particle B having a degree of hydrophobization of 30% or more and a volume average particle size of 0.01-3μm. The antibacterial inorganic particle B is an oxide containing zinc, titanium, copper or nickel. An addition amount ratio of the antibacterial inorganic particle A to the antibacterial inorganic particle B is 1:7-1:0.25. COPYRIGHT: (C)2005,JPO&NCIPI
