PROBLEM TO BE SOLVED: To make an artificial cranial bone member compatible to the shape of an actual bone deficit part by constituting the artificial cranial bone member by a material having bioaffinity and bending the member into a desired shape by a tool or forming the member into one with thickness which can be notched. SOLUTION: By using ceramic materials such as alumina and apatite and a glass material such as bioglass, an artificial cranial bone member 10 is made one without bio-pseudo harmfulness or one with bioaffinity. In the artificial cranial bone member 10, many grooves 3 extending in radiation shapes and many concentric circular grooves 3 with a substantially spherical shell-like top part performing prosthesis for a loss part of the cranial bone as a center are formed so as to be intersected each other. Many fan blocks 4 partitioned by these grooves 3 are bent by tools such as pinchers, scissors and flat pliers and are divided by thickness which can be notched. As a result, the cranial bone member 10 can be made compatible to the shape of an actual bone deficit part.
