Abstract
An inertial measurement device includes a first inertial sensor having a first detection axis, a second inertial sensor having a second detection axis defined in a direction opposite to the first detection axis, and a processing circuit configured to execute self-diagnosis based on whether a ratio of an amplitude of an output of the first inertial sensor to an amplitude of an output of the second inertial sensor is within a reference range.
