摘要 PROBLEM TO BE SOLVED: To provide a vibration element that has a simpler configuration and can reduce manufacturing cost.SOLUTION: There are formed a power feeding path that includes a first torsion beam 101, second torsion beam 102, first conductive member 201, and first electrode 501, and a power feeding path that includes a third torsion beam 103, fourth torsion beam 104, second conductive member 202, and second electrode 502. A first magnet group is arranged that generates a magnetic field acting on a current flowing through the first torsion beam 101 and a current flowing through the fourth torsion beam 104. A second magnet group is arranged that generates a magnetic field acting on a current flowing through the second torsion beam 102 and a current flowing through the third torsion beam 103. With this configuration, a vibration part 21 causes torsional vibration.
