<p>PROBLEM TO BE SOLVED: To provide a vibration piece capable of suppressing vibration leak and restraining a CI value to a low value even when downsizing is executed, and to provide a vibrator having the vibration piece, an oscillator, an electronic device and a mobile unit.SOLUTION: A vibration piece 1 comprises: a base 12; and a pair of vibration arms 20, 22 extending along the Y-axis direction from the base 12 and aligned along the X-axis direction. A distance Wa between centers of a pair of vibration arms 20, 22 along the X-axis direction is longer than the length L of the base 12 along the Y-axis direction, and two bonding members 35 fixed to an outside are aligned along the Y-axis direction on one main surface of the base in the Z-axis direction.</p> |
