PURPOSE:To facilitate the measurement of characteristics and to attain to increase assembling efficiency, by changing the mutual positional relation in the superposition of a substrate to which a pressure sensor having a plurality of gauges is mounted and a substrate to which circuit parts are attached. CONSTITUTION:A pressure sensor 102 is attached to a substrate 101 and, according to necessity, resin coating is applied thereto. In the next step, pressure is added to the sensor 102 and characteristics are measured to select a most excellent gauge. Because no circuit parts are attached to the substrate 101, there is no damage and measurement can be easily performed. Subsequently, the substrate 101 is superposed to a substrate 110 and the mutual position thereof is selected to bring the connector electrodes 111... on the substrate 110 into contact with the connector electrodes of a group connected to the gauge selected from the connector electrodes 104... on the substrate 101. In this state, electrodes 104..., 111... are mutually soldered and the trimmings of resistors 114, 115 on the substrate 110 are subsequently performed to carry out the setting of circuit constant. |
