Abstract
To provide a combined sensor that can detect a plurality of physical quantities. With the combined sensor, it is possible to realize, while maintaining performance, a reduction in size and a reduction in costs by increasing elements that can be shared among respective sensors. A weight Mand a detection electrode DTEused in an angular-velocity detecting section are also used as a reference capacitive element of a Z-direction-acceleration detecting section configured to detect acceleration in a Z direction. That is, in the Z-direction-acceleration detecting section, a detection capacitive element including the weight Mand the detection electrode DTEconfiguring the angular-velocity detecting section is used as a reference capacitive element for a detection capacitive element formed by a detection electrode DTEand a weight M
