PROBLEM TO BE SOLVED: To avoid an interference between a screw for fixing a bone plate, and a through hole formed in the tibia to transplant a ligament in an anterior cruciate ligament reconstructive operation.SOLUTION: The bone plate 1 includes a strip-like body part 1a arranged along the tibia on the higher side face of the tibia, and an intersecting part 1b provided at one end of the body part 1a to extend in a direction to intersect the longitudinal direction of the body part 1a. The intersecting part 1b is provided with a plurality of threaded holes 5a, 5b arranged at a space in the direction to intersect the longitudinal direction and penetrating a plate thickness direction. Out of the threaded holes 5a, 5b, the anterior threaded hole 5a closest to the anterior surface side of the tibia when the body part 1a is arranged along the tibia has an inner diameter dimension larger than that of the other threaded hole 5b.
