摘要： [PROBLEMS] To provide a stress sensor capable of measuring, with high sensitivity, a stress fluctuation fluctuated after setting relative to a stress normally applied to a structural body. [MEANS FOR SOLVING THE PROBLEMS] This device comprises a cylindrical body (4) having an outer peripheral part closely fitted to a circular hole (3) formed in a structural member to be measured such as a bearing wall (1) at a position where the measurement of internal stress is required and having an axis crossing perpendicularly to the line of force of the stress which must be measured, a gauge fixing plate (25) installed in the inner hole (3) of the cylindrical body (4) so that the gauge fixing surface thereof crosses perpendicularly to the axis of the cylindrical body (4), and a plurality of strain gauges (r1) to (r4) installed on the gauge fixing plate (25) so that a strain detection direction is aligned with a radial direction with respect to the axis of the circular hole to detect the circular strain of the circular hole (3).
