PURPOSE: A ceramic ball type artificial fish reef is provided to have a honeycomb-shaped porous inner structure which has an excellent absorption and adhesion since red clay and sericite, which are natural soil, are main components thereby facilitating the attachment of marine algae, increasing habitat density by increasing a moisture control function and pollutant adhesion, and improving seawater purification efficiency. CONSTITUTION: A ceramic ball type artificial fish reef(100) includes a pair of an upper part fish reef(110) and a lower part fish reef(120) which have semi-spherical shapes to form a space where different types of seaweed and fish inhabit, to be mutually faced vertically, and to be butt-jointed by a connection unit to form a ball shape. The upper part and the lower part fish reef are respectively formed with multiple side entry fish paths(111), which form a connection between an inner space and the outside, in the circumferential direction with a fixed interval. The upper part fish reef is formed with a circular upper part entry fish path(113) on the center of the side end of the ball, while the lower part fish reef is formed with a circular lower part entry fish path(123) on the center of the side end of the ball. A manufacturing method of the upper part and the lower part fish reef is as follows. The mixture, which is dry-mixed, is composed of the followings of, in parts by weight per100 parts by weight of red clay powder: sericite powder: 33-100 blast furnace slag powder: 46-120 anhydrous gypsum powder: 6-50 silica fume powder: 3-20 slaked lime powder: 6-50 pumice which is a aggregated material and 7-13mm in grain size: 33-100 and bottom ash: 400 -700. The mixture is added with the followings of, in parts by weight per 100 parts by weight of red clay powder: natural inorganic element additive: 6-30 high performance water reducing admixture: 0.5-3 and water: 6-200. The mixture is input into a mold with a semi-spherical fish reef block to be molde
