An angular velocity sensor structured so as to reduce the application of external vibrations to tuning fork (21) as described below. Supporting plate (54) having placement part (57) for placing first rubber body (35) over the top face thereof is placed above the top face of second base (50) via at least two supports (55) so as to provide space (54a) between the top face of second base (50) and the supporting plate. First cover (34) and fist base (31) housing tuning fork (21) are placed on first rubber body (35). Further placed on first cover (34) is second rubber body (37). The top face of supporting plate (54) and the inner ceiling of second cover (53) compress and hold first rubber body (35) and second rubber body (37) therein. <IMAGE>
