Physical Quantity Sensor, Inertial Measurement Device, Vehicle Positioning Device, Portable Electronic Apparatus, Electronic Apparatus, And Vehicle

A physical quantity sensor comprising:

• a substrate;
• a first detection electrode that includes a first electrode finger;
• a first spring that supports the first detection electrode in a displaceable manner in a first direction with respect to the substrate;
• a second detection electrode that includes a second electrode finger which is disposed at a distance from the first electrode finger in the first direction;
• and
• a second spring that supports the second detection electrode in a displaceable manner in the first direction with respect to the substrate,
• wherein, when an acceleration in the first direction is applied, a displacement amount of the first detection electrode in the first direction is equal to a displacement amount of the second detection electrode in the first direction.
