The purpose of the present invention is to provide an eco-friendly tile which is useful to human bodies by adding wooden flour to middle and lower layers composing a PVC tile which is not useful to human bodies; to provide a tile which emits components useful to human bodies such as far-infrared radiation by adding pozzolan useful to human bodies to the middle and lower layers composing the tile; and to provide a tile which emits no harmful components of an adhesive generated when bonding an upper layer, the middle layer, and the lower layer with the adhesive by bonding the upper layer, the middle layer, and the lower layer with a thermal bonding method. The present invention includes the upper layer composed of PVC; the middle layer composed of 20-30 wt% of wooden flour (60-120 mesh), 40-60 wt% of PVC, 3-15 wt% of pozzolan, and 3-15 wt% of calcium carbonate; and the lower layer composed of 20-30 wt% of wooden flour (60-120 mesh), 40-70 wt% of PVC, and 6-30 wt% of pozzolan. |
