PURPOSE:To reduce electrostatic induced noise and to improve sensing characteristics by forming an earthed wiring pattern between wiring patterns connected to a current loop type stretcher and wiring patterns connected to detectors. CONSTITUTION:The stretcher wiring patterns 6a, 6b and sense signal wiring patterns 8a-8c are connected to the current loop type stretcher 7 and the detectors 9a, 9b respectively through bonding wires. The earthed wiring pattern 11 is inserted between the patterns 6a, 6b and 8a-8c. Thus, almost all stray capacity between the patterns 6a, 6b and 8a-8b is closed between the patterns 6a, 6b and 11 and the stray capacity contributing to induction from the patterns 6a, 6b to 8a-8c is extremely reduced. |
