The present invention herein provides antibacterial zeolite particles whose ion-exchangeable ions have completely or partially been replaced with silver ions and zinc ions, wherein the ratio (A/B) of the silver ion concentration (A) to the zinc ion concentration (B) in the antibacterial zeolite particles increases in the direction along the depth of each zeolite particle. The antibacterial zeolite particles show excellent discoloration-resistant characteristics, while maintaining their excellent antibacterial activities. Accordingly, the antibacterial zeolite particles can suitably be applied to all sorts of products that are required to have antibacterial properties.
