PROBLEM TO BE SOLVED: To provide a sensor element capable of effectively reducing unnecessary vibration, and further to provide a physical quantity sensor provided with the sensor element, an electronic apparatus and a movable body.SOLUTION: A sensor element comprises: a base portion 21; a vibration body including drive vibration arms 221 and 222 extending in a y-axis direction from the base portion 21; and coupling portions 261 through 264 supporting the vibration body. When a frequency of a drive vibration mode where the drive vibration arms 221 and 222 are driven to vibrate in an x-axis direction is represented by fd and a frequency of a y direction vibration mode where the vibration body vibrates in the y-axis direction in accompaniment with deformation of the coupling portions 261 through 264 is represented by fy, fd and fy satisfy a relation of 0.7≤fd/fy.SELECTED DRAWING: Figure 1 |
