Claim 0:
1. A gyro sensor comprising:
three mutually orthogonal axes being defined as an X-axis, a Y-axis, and a Z-axis;
a substrate; and
an element unit that is supported on an upper surface of the substrate, is located on a plus side of the Z axis, and is configured to detect an angular velocity based on a change in capacitance, wherein
the element unit comprises:
a fixed section fixed to the upper surface of the substrate;
a mass section configured to be displaced in an X-axis direction along the X-axis parallel to the upper surface of the substrate;
a driving section that drives the mass section in the X-axis direction;
a first detecting section that is connected to the mass section and is configured to be displaced in a Z-axis direction along the Z-axis;
a second detecting section that is connected to the mass section and is configured to be displaced in the Z-axis direction;
a first elastic section connecting the first detecting section and the fixed section;
a second elastic section connecting the second detecting section and the fixed section;
a first fixed detecting section facing the first detecting section and spaced apart from the first detecting section; and
a second fixed detecting section facing the second detecting section and spaced apart from the second detecting section.
