A bone plate configured to be applied to a side surface of a shin bone where a side surface of an epiphysis protrudes relative to a side surface of a diaphysis, the bone plate being fixable to the side surface of the shin bone by bone fixation members, the bone plate comprising: a long-plate-shaped main section that is configured to be disposed on the side surface of the diaphysis and that has one or more through-holes (6a, 6b, 6c, 6d) into which the bone fixation member is inserted; a transverse section that is configured to be disposed on the side surface of the epiphysis and that is disposed at an one end side of the main section and also that has one or more through-holes (7a, 7b, 7c, 7d) into which the bone fixation member is inserted; and a coupling section coupling the transverse section and the main section to each other, wherein the main section is twisted relative to the transverse section around an axis that is parallel to a longitudinal axis of the main section, and wherein, when the bone plate is viewed in a transverse direction of the main section, the bone plate has a shape in conformity to the side surface of the shin bone such that the coupling section is inclined relative to a longitudinal direction of the main section and the main section and the transverse section are bent to have a cranked shape in which the main section and the transverse section are offset relative to each other in a thickness direction of the bone plate, wherein the bone plate comprises a lower surface which is configured to be disposed on the side surface of the shin bone and an upper surface that is opposed to the lower surface and that is configured to be disposed opposite the side surface of the shin bone, wherein a center axis of at least one of the through-holes (6a, 6b, 6c, 6d, 7a, 7b, 7c, 7d) in each of the main section and the transverse section is inclined relative to a normal to a tangent plane of the upper surface, wherein the upper surface has a protrusion provided around the at least one through-hole (6a, 6b, 6c, 6d,7a, 7b, 7c, 7d), and wherein the protrusion is provided at a side where an angle formed between the center axis and the tangent plane is an obtuse angle. a long-plate-shaped main section that is configured to be disposed on the side surface of the diaphysis and that has one or more through-holes (6a, 6b, 6c, 6d) into which the bone fixation member is inserted; a transverse section that is configured to be disposed on the side surface of the epiphysis and that is disposed at an one end side of the main section and also that has one or more through-holes (7a, 7b, 7c, 7d) into which the bone fixation member is inserted; and a coupling section coupling the transverse section and the main section to each other, wherein the main section is twisted relative to the transverse section around an axis that is parallel to a longitudinal axis of the main section, and wherein, when the bone plate is viewed in a transverse direction of the main section, the bone plate has a shape in conformity to the side surface of the shin bone such that the coupling section is inclined relative to a longitudinal direction of the main section and the main section and the transverse section are bent to have a cranked shape in which the main section and the transverse section are offset relative to each other in a thickness direction of the bone plate, wherein the bone plate comprises a lower surface which is configured to be disposed on the side surface of the shin bone and an upper surface that is opposed to the lower surface and that is configured to be disposed opposite the side surface of the shin bone, wherein a center axis of at least one of the through-holes (6a, 6b, 6c, 6d, 7a, 7b, 7c, 7d) in each of the main section and the transverse section is inclined relative to a normal to a tangent plane of the upper surface, wherein the upper surface has a protrusion provided around the at least one through-hole (6a, 6b, 6c, 6d,7a, 7b, 7c, 7d), and wherein the protrusion is provided at a side where an angle formed between the center axis and the tangent plane is an obtuse angle.
