To provide an angle velocity detection apparatus for correcting an output error caused by the inclination of the mounting angle of an angle velocity sensor in an angular velocity detection.
An angular velocity detection apparatus comprises a first angular velocity sensor used for detecting vibration around an axis parallel to a second direction perpendicular to a first direction, a second angular velocity sensor used for detecting vibration around an axis parallel to the first direction, and a control part that controls the first and second angular velocity sensors. The control part performs an angle error correcting processing that corrects an output error caused by the inclination of mounting angle of the second angular sensor by using a correction coefficient that is a ratio of an amplitude output from the second angular sensor to an amplitude output from the first angular sensor, when a first vibration around an axis parallel to the second direction is given in a state the second vibration around an axis parallel to the first direction is not given.
