Abstract
A physical quantity sensor includes a driven section and a drive spring that supports the driven section so that the driven section is displaceable in a first direction. The drive spring has a serpentine shape and includes a plurality of spring structures extending in a second direction that intersects a first direction. At least one of the spring structures has a thin section that is thinner in a third direction that intersects the first and second directions than the other portions of the drive spring.
