Abstract
The present invention herein provides antimicrobial zeolite which hardly causes any color change with the elapse of time even when it is incorporated into a resin to form an antimicrobial resin composition. The present invention thus relates to antimicrobial zeolite which comprises zeolite whose ion-exchangeable ions are partially or wholly replaced with hydrogen ions and silver ions; and an antimicrobial resin composition which comprises the foregoing antimicrobial zeolite in an amount ranging from 0.05 to 80% by mass.
