Abstract
Two sides of a single metal plate are bent to form the structure of a spring terminal having two spring portions. In the spring terminal having such a structure, the two spring portions are different from each other in a natural frequency. For this reason, when external vibrations are applied to a pressure sensor, even if one of the two spring portions of the spring terminal resonates with the external vibrations, the other spring portion can keep the electric connection between a circuit in a substrate and a terminal.
