In a mechanical quantity measuring device (1) having a sensor chip (2) which outputs a sense output (S) corresponding to a mechanical quantity acting on the object to be measured (4), and a flexible wiring board (3) which supports the sensor chip (2) and has a wire (6) to lead out the sense output (S) to outside, and in which in measuring the mechanical quantity, the sensor chip (2) and the flexible wiring board (3) are attached to the object to be measured (4), a cutout (5) is provided on the flexible wiring board (3) near the sensor chip (2) and on the side where the wire (6) is arranged for the sensor chip (2). Thus, change in the sense output (S) with time can be restrained. |
