Abstract
An acceleration and angular velocity detector comprises a body mass, a flexible portion, which is connected to the body mass, that deforms in consonance with a displacement of the body mass, and a peripheral support for supporting the flexible portion. A vibration device causes the body mass to vibrate circularly in two dimensions. A displacement detection device independently detects displacements of the body mass in three axes directions and outputs a signal and a signal processor calculates acceleration in the three axes directions and angular velocities around three axes by employing the signal that is output by the displacement detection device.
