Abstract: A bone plate includes a plate body portion extending in a lengthwise direction, a head portion extending from one end portion in the lengthwise direction of the plate body portion, and tabs provided on the outer side of an outer peripheral portion of the head portion. The tabs comprise first-type tabs and side by side with each other, and a second-type tab located on one outside of the first-type tabs. The first-type tabs respectively include first connecting portions that are bendable and have a cross-sectional area in a widthwise cross section that is smaller than the cross-sectional area of the outer shape of the first tab body portions. The second-type tab includes a second connecting portion that is bendable and twistable and has a smaller cross-sectional area in a widthwise cross section than the first connecting portions.
