The invention relates to a humeral component of a shoulder joint prosthesis, comprising a bearing body (38), a shaft (32) and a transition area (34) which is arranged between the bearing body (38) and the shaft (32). One surface of the transition area (34) comprises, on a large area, a structure in the form of projections (48) for attaching bone fragments and/or muscle attachments and/or tendon attachments. The projections (48) are arranged discretely in a distributed manner on the surface of the transition area (34) and essentially in the proximal-distal direction and also essentially in the direction of the periphery.
