PROBLEM TO BE SOLVED: To provide a stress sensor capable of accurately measuring stresses acting on a structure even if it is a structure having a complicated shape and a plurality of different fixed points or a structure on which external forces act in directions different from each other. SOLUTION: This sensor is equipped with a substrate 1 having at least one principal plane 1a, a first strain gage 2 having a pair of resistors 4 and 5 insulated from each other and crosswise disposed on the plane 1a of the substrate 1, and a second strain gage 3 having a pair of resistors 6 and 7 insulated from each other and crosswise disposed on the plane 1a of the substrate 1, neither of the pair of resistors 6 and 7 being in line with or parallel to either of the pair of resistors 4 and 5 of the strain gage 2.
