Physical Quantity Sensor, Inertia Measurement Device, Vehicle Positioning Device, Electronic Apparatus, And Vehicle

Abstract

A physical quantity sensor includes a substrate, a first sensor element that is positioned on one main surface of the substrate and includes a first fixed portion fixed to the substrate, a second sensor element that is positioned on the one main surface of the substrate and includes a second fixed portion fixed to the substrate, a first recess portion that is open to the other main surface of the substrate and is disposed so as to overlap the first fixed portion in plan view of the substrate, and a second recess portion that is open to the other main surface of the substrate and is disposed so as to overlap the second fixed portion in plan view of the substrate, and in which the first recess portion and the second recess portion are disposed so as to be separated from each other.
