Abstract
An acceleration and angular velocity detection device includes a first oscillation element and a second oscillation element that are movable in a direction along a first axis and a direction along a second axis, an oscillating portion oscillating the first and second oscillation elements in opposite directions along the first axis, a first detection capacitance element and a second detection capacitance element whose capacitances change in a complementary way in accordance with a displacement of the first oscillation element, a third detection capacitance element and a fourth detection capacitance element whose capacitances change in a complementary way in accordance with a displacement of the second oscillation element, a charge amplifier having a fully differential structure, and a detecting portion detecting an acceleration and an angular velocity of a rotation.
