PROBLEM TO BE SOLVED: To provide an artificial fishing reef capable of validly using woods whose thicknesses or lengths are different as a portion of a fishing reef without connecting the woods with each other. SOLUTION: This artificial fishing reef is provided with: a fishing reef body formed with an opening so that an internal space configured to store woods can communicate with the outside; and an outflow prevention means mounted on the fishing reef body such that the opening is covered, and configured to prevent the wood stored in the internal space in such a state that the internal space communicates with the outside from flowing out of the opening.
