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.
