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 100:510; grinding water and the antimicrobial glaze into the antimicrobial glaze in a weight ratio of 56:45; and dotting antimicrobial glaze on the ground glaze; finally, rapidly firing the ceramic tile and the antimicrobial glaze into an antimicrobial ceramic tile.

Ceramic tile having a ceramic base layer and a cover glaze layer including a printed pattern, where the surface of the ceramic tile has a relief having structural features corresponding to the printed pattern. The relief being basically formed as a plurality of excavations present in the generally plane upper surface of the ceramic tile and the structural features have a depth such that they are completely situated above the ceramic base layer.
