Abstract

PURPOSE:To prepare the element with small error in measurement by dividing in two at least one of the resistors of a bridge circuit and by arranging each resistor in the regions of maximum extension and contraction strain in such a manner that wirings between the resistors are not crossed and not passed through the maximum strain region. CONSTITUTION:An insulator film 10, a thin resistor film 11' and a thin connecting part film 12' are laminated in sequence on the strain generating part 5 of a beam body 1. Next, etching is applied thereto with a pattern shown in Fig. B left as it is and further the thin connecting part film in a part on the regions of maximum extension and contraction strain is removed by etching, whereby resistant elements 11A1-A2...11D1-D2 are formed. The bridge circuit is formed by arranging resistors 11B1-B2 between resistors 11A-A2, which are formed through division in two, two pairs of lead wires 13 are connected to the circuit, voltage is impressed from one pair and an output meter is connected to the other pair, whereby the strain is detected. Thus, a circuit constituted in such a manner that connecting wires 12 are not crossed and not passed through the maximum strain region is obtained and thereby the element capable of performing measurement with small error can be mass-produced.
