Abstract
Screws are tightened at desired angles while avoiding a troublesome bone-plate deforming task at an operation site and risks, such as the occurrence of metallic powder and implant fracture. Provided is a bone plate (1) that is formed into a band plate disposed along a bone surface and that includes a plurality of screw holes (5a) that are arranged at intervals in a longitudinal direction and that penetrate in a plate thickness direction. At least one of the screw holes (5a) that is located at an end in a longitudinal direction has a female thread (6) formed by performing tapping along an axis (C1) of a prepared hole and along at least one of axes (C2) and (C3) inclined with respect to the axis.
