Abstract
A gyro sensor includes a base, a first connection arm and a second connection arm that extend from the base in opposite directions along an X axis, a first drive oscillation arm that extends from the first connection arm along a Y axis, a second drive oscillation arm that extends from the second connection arm along the Y axis, and a first detection oscillation arm and a second detection oscillation arm that extend from the base in opposite directions along the Y axis, and each of the first drive oscillation arm and the second drive oscillation arm has an oscillation component along the X axis and an oscillation component along a Z axis.
