ABSTRACT:
A stress sensor in which the direction and magnitude of a stress being applied to a post (6) bonded to or integrated with the surface of an insulating board (3) can be grasped from variation in the resistance of a plurality of resistor elements (8) being stimulated by application of the stress while suppressing variation in the shape of each resistor (2). The resistor element (8) comprises a resistor (4) formed, by screen print, between a pair of electrodes for the resistor element, i.e. circuit pattern electrodes (1), arranged on the surface of the insulating board (3). The electrode is connected, through a conductor (9), with a board terminal part (5) arranged at one end of the insulating board (3). The electrode (1) and the conductor (9) or a print accuracy adjusting member (7) have a constant height from the surface of the insulating board (3). Arrangement of the conductor (9), the electrode (1) and the print accuracy adjusting member (7) is entirely identical or similar for the plurality of resistor elements (8) in the vicinity thereof.
