Abstract:
1. A physical quantity detection element comprising: a base part; when coordinate axes having an X-axis passing through an origin as a center of gravity of the base part and a Y-axis passing through the origin and being orthogonal to the X-axis are defined, and when a region in which both an X-coordinate and a Y-coordinate take positive values is defined as a first quadrant, a region in which the X-coordinate takes a negative value and the Y-coordinate takes a positive value is defined as a second quadrant, a region in which both the X-coordinate and the Y-coordinate take negative values is defined as a third quadrant, and a region in which the X-coordinate takes a positive value and the Y-coordinate takes a negative value is defined as a fourth quadrant, a first connection part and a second connection part connecting to the base part and provided at both sides of the base part along the X-axis; a first drive vibrating arm and a second drive vibrating arm respectively extending from the first connection part in opposite directions to each other along the Y-axis; a third drive vibrating arm and a fourth drive vibrating arm respectively extending from the second connection part in opposite directions to each other along the Y-axis; a first drive detection vibrating arm extending in the first quadrant direction and obliquely extending with respect to the X-axis, the first drive detection vibrating arm directly extending from the first drive vibrating arm without the first connection part intervening therebetween; a second drive detection vibrating arm extending in the fourth quadrant direction and obliquely extending with respect to the X-axis, the second drive detection vibrating arm directly extending from the second drive vibrating arm without the first connection part intervening therebetween; a third drive detection vibrating arm extending in the second quadrant direction and obliquely extending with respect to the X-axis, the third drive detection vibrating arm directly extending from the third drive vibrating arm without the second connection part intervening therebetween; and a fourth drive detection vibrating arm extending in the third quadrant direction and obliquely extending with respect to the X-axis, the fourth drive detection vibrating arm directly extending from the fourth drive vibrating arm without the second connection part intervening therebetween.
