A method is specified for producing a strain gauge arrangement (14) on a surface of a machine element (2), particularly a bearing ring (3) or a shaft (17), wherein a deformation-sensitive measurement layer (6) and a protective layer (8) situated thereabove are applied to the surface. The protective layer (8) is locally removed by laser processing and the exposed measurement layer (6) is contacted electrically. A machine element (2), particularly a bearing ring (3) or a shaft (17), with a strain gauge arrangement (14) produced according to the method is also provided.
