Abstract
Disclosed is a gyro sensor, which comprises a primary base plate () and a support base plate () which are superimposed on one another. The primary base plate () is provided with a driven mass body () to be driven in such a manner as to be vibrated in a direction intersecting with a surface of the support base plate (), and a detection mass body () coupled with the driven mass body () through a drive spring () and adapted to be displaceable in a plane along the support base plate (). Two detection springs () extending in the arranging direction of the driven mass body () and the detection mass body () are connected, respectively, to opposite side of the detection mass body (), and the other ends of the detection springs () are connected together through a coupling segment (). A fixing segment () provided at a longitudinally intermediate portion of the coupling segment () is fixed to the support base plate (). A member formed by integrating the driven mass body () and the detection mass body () through the drive spring () is supported relative to the support base plate () by the detection springs () in a cantilever manner.
