A six-legged type piezoelectric vibration gyroscope having a pair of exciting arms extending from a body ( 2 ) in a first direction (A 1 ) with a space therebetween, one non-exciting arm ( 3 c) extending in the first direction between the exciting arms from the body, a pair of detecting arms ( 4 a, 4 b) extending from the body in a second direction (A 2 ) with a space therebetween, and one non-detecting arm ( 4 c) extending in the second direction between the detecting arms from the body. The exciting arms are coupled with a drive-side electrode. The detecting arms are coupled with a detection-side electrode. The exciting arms, non-exciting arm, detecting arms, and non-detecting arm respectively consist of a piezoelectric. The respective exciting arms differ in width size from the non-exciting arm. The respective exciting arms differ in width size from the respective detecting arms. The respective exciting arms differ in width size from the non-detecting arm.
