The present invention provides an antimicrobial ceramic tile and manufacturing method thereof. A manufacturing method of an antimicrobial ceramic tile comprises: grinding soils into slurries; drying the slurries into powders by hot air; pressing the powders into a green body through a molding machine; dotting or spraying or showering a glaze slurry on the surface of the green body to form an engobe; dotting the glaze slurry on the engobe to form a ground glaze; mixing a surface glaze and an antimicrobial material into an antimicrobial glaze in a weight ratio of 100:5˜10; grinding water and the antimicrobial glaze into the antimicrobial glaze in a weight ratio of 5˜6:4˜5; and dotting antimicrobial glaze on the ground glaze; finally, rapidly firing the ceramic tile and the antimicrobial glaze into an antimicrobial ceramic tile.
