A vibrator has a driving vibration piece 2A, a detection vibration piece and a base portion connecting the driving and detection vibration pieces. The driving vibration piece 2A is composed of a bending vibration piece having a pair of surfaces 2c and 2d parallel with each other and a pair of side faces 2a and 2b. The driving vibration piece 2A has a ratio (WD/TD) of a width WD to a thickness TD of not smaller than 1.5 and not larger than 2.4.",
