Abstract: A strain element (10), which is configured such that a frame portion (11) and a central portion (12) are connected by arm portions (20) to (22), is masked except for the arm portions (20) to (22) where a strain gauge (A1) and the like are to be disposed, and then peening is carried out. With this, a compressive residual stress layer is formed on four sides of each of the arm portions (20) to (22). When the strain element (10) receives a load resulting from an external force, the arm portions (20) to (22) elastically deform; however, due to the compressive residual stress layer thus formed, the arm portions (20) to (22) are less prone to fatigue failure. When projection of a shot material is carried out as peening, the surface roughness of the arm portions (20) to (22) increases, the adhesion of strain gauges improves, detection accuracy improves, and stable measurement can be ensured.
