Proposed is a horizontally located angular velocity sensor hardly affected by a translational acceleration in a lateral direction, and in which a fixed section is easily fixed. The angular velocity sensor includes a fixed section fixed on a support surface. On both sides of the fixed section, an arm section of an upper detection arm and a pair of upper drive arms extending along a plane parallel to the support surface, and an arm section of a lower detection arm and a pair of lower drive arms extending along the plane parallel to the support surface are coupled, respectively. The upper detection arm and the pair of upper drive arms are coupled without the fixed section in between, and the lower detection arm and the pair of lower drive arms are coupled without the fixed section in between.
