PROBLEM TO BE SOLVED: To obtain an antimicrobial lamellar silicate improved in water resistance, chemical resistance, heat resistance, weather resistance and antimicrobial effect durability by carrying an antimicrobial organic compound between the lamellae of a hydrogen type lamellar silicate. SOLUTION: This antimicrobial lamellar silicate is obtained by immersing 100 pts.wt. of a lamellar silicate having an average particle diameter of <=10μm and a cation exchange capacity of >=0.1meq/g and containing a hydrogen ion as an ion-exchangeable ion in an antimicrobial organic compound solution having a pH of 0.1-13, stirring the mixture at 40-60 deg.C for 0.5-72hr at a rotation rate of 10-1000 turns/min, and subsequently drying the treated silicate. >=0.1 pt.wt. of the antimicrobial organic compound is carried between the lamellae of the lamellar silicate. Conditions for producing the antimicrobial silicate are especially not limited, and may suitably be changed in dependence on the kind of the used antimicrobial organic compound, the kind and carrying capacity of the hydrogen type lamellar silicate, etc.
