An antimicrobial and deodorant composition and an antimicrobial deodorization method using the same are provided to suppress the activity of microorganisms generating the offensive odor by components containing antimicrobial inorganic metal and the composition containing specific polymer. An antimicrobial and deodorant composition consists of components(A) containing antimicrobial inorganic metal, nitrogen containing polymer(B), and polymer water-soluble glucan or sugar-alcohol(C) having alpha-1,4-glucoside linkage. The nitrogen containing polymer contains basic poly amino acid. The component contains at least one kind of antimicrobial inorganic metal selected from silver, copper, and zinc. The antimicrobial and deodorant composition is sprayed in the maximum particle diameter less than 300 micrometers. The polymer water-soluble glucan or sugar-alcohol continuously deodorizes heavy chain aldehydes and remains on the surface of cloth products.
