An artificial fishing reef block comprises: a plurality of depression grooves(11) which are formed in both sides so that the small fishes can come in and out; and a plurality of mounting holes(2) which are formed inside so that algae, shellfish, and minute animal can adhere closely. The mounting hole is formed into the rectangle groove in order to extend the attachment surface. The circumference surface of the mounting hole comprises a curved face(21) to extend the attachment face.
