Gyro module
First Claim
1. A gyro module, comprising:
- two gyro element pieces outputting a signal, the signal being obtained by combining a signal of an angular velocity of a first detection axis and a signal of an angular velocity of a second detection axis; and
an arithmetic circuit for performing an addition and a subtraction with respect to the signal outputted from the two gyro element pieces, wherein the two gyro element pieces are a first gyro element piece and a second gyro element piece; and
the first and second gyro element pieces are arranged such that a detection sensitivity polarity of the first detection axis of the first gyro element piece is same as that of the second gyro element piece, and a detection sensitivity polarity of the second detection axis of the first gyro element piece and that of the second gyro element piece are inverted.

Abstract
A gyro module includes: two gyro element pieces outputting a signal, the signal being obtained by combining a signal of an angular velocity of a first detection axis and a signal of an angular velocity of a second detection axis; and an arithmetic circuit for performing an addition and a subtraction with respect to the signal outputted from the two gyro element pieces. The two gyro element pieces are a first gyro element piece and a second gyro element piece. The first and second gyro element pieces are arranged such that a detection sensitivity polarity of the first detection axis of the first gyro element piece is same as that of the second gyro element piece, and a detection sensitivity polarity of the second detection axis of the first gyro element piece and that of the second gyro element piece are inverted.
