Physical Quantity Sensor, Physical Quantity Sensor Device, Complex Sensor Device, Inertial Measurement Unit, And Vehicle

A physical quantity sensor comprising:

• a substrate;
• a support portion fixed to the substrate;
• a movable body which is displaceable in a first direction with respect to the support portion and has a movable electrode provided therein;
• and
• a fixed electrode fixed to the substrate,
• wherein the fixed electrode includes a first fixed electrode, a second fixed electrode, a third fixed electrode, and a fourth fixed electrode, the first fixed electrode being positioned on one side of a second direction orthogonal to the first direction with respect to the support portion and having a first fixed electrode finger provided therein, the second fixed electrode being provided to be separated from the first fixed electrode and having a second fixed electrode finger provided therein, the third fixed electrode being positioned on the other side of the second direction with respect to the support portion and having a third fixed electrode finger provided therein, and the fourth fixed electrode being provided to be separated from the third fixed electrode and having a fourth fixed electrode finger provided therein, and
• the movable electrode includes a first movable electrode, a second movable electrode, a third movable electrode, and a fourth movable electrode, the first movable electrode having a first movable electrode finger provided to face the first fixed electrode finger in the first direction, the second movable electrode having a second movable electrode finger provided to face the second fixed electrode finger in the first direction, the third movable electrode having a third movable electrode finger provided to face the third fixed electrode finger in the first direction, and the fourth movable electrode having a fourth movable electrode finger provided to face the fourth fixed electrode finger in the first direction.
