Abstract: A torque wrench having ease of operation compatible with improved accuracy of measurement. The torque wrench includes a tightening portion, a housing having a front side cover part and a back side grip part and a shaft-like strain body that is contained inside the housing. First distortion sensors and second distortion sensors are arranged on the strain body at spaced points in the axial direction of the strain body for measuring an amount of distortion of the strain body. A microprocessor chip has functions including computation of a tightening torque which is corrected for errors due to changes in a point of effort where a tightening force is applied by a user. The correction is based on the detection result of the first distortion sensors and the second distortion sensors. An output portion outputs the corrected tightening torque measurement value.
