PROBLEM TO BE SOLVED: To obtain the subject silicate hardly changing in color, having excellent weather resistance and heat resistance by supporting isothiazoline-based fungicidal organic compound on between layers of laminar silicate comprising an ion exchange ion being an alkaline earth metal. SOLUTION: This silicate is obtained by supporting (B) an isothiazoline-based fungicidal organic compound (e.g. 2-n-octyl-4-isothiazolin-2-one, etc.), on between (A) a laminar silicate (e.g. smectites laminar silicate, etc.), comprising an ion exchange ion being an alkaline earth metal. Preferably >=0.1 pts.wt. of the component B is supported based on 100 pts.wt. of the objective silicate. The objective silicate is useful as a fungicidal agent which is mixed with various materials and provides excellent fungicidal effect, for example, can be mixed with a rubber such as a silicone, a plastic such as vinyl chloride resin, etc. In mixing a material with the silicate and molding, preferably 0.05-30 pts.wt. of the silicate is added to 100 pts.wt. of the material to be provided with fungicidal properties.
