A ligament fixture to be inserted and fixed into a fitting hole formed in an in-vivo bone is provided, and includes an in-vivo degradable and absorbable material which is a polymer-bioceramic composite material. The ligament fixture has at least one pair of opposed surfaces which are inclined faces gradually getting closer to each other toward to a front-end side of the ligament fixture and which form a wedge shape having a resistance imparting parts on each of the inclined faces. The ligament fixture includes a front-end part having a cross-sectional profile smaller than a cross-sectional profile of the fitting hole, and a main body part continuing from the front-end part, the main body part including a section having a cross-sectional profile larger than the cross-sectional profile of the fitting hole.
