PROBLEM TO BE SOLVED: To provide a piezoelectric vibrator in which the vibration property is excellent, an electronic component and an oscillator.SOLUTION: In a mesa-shaped or inverse-mesa-shaped crystal piece 2 in which heights of a principal surface 21 and of an edge 22 are different, a first exciting electrode and a second exciting electrode are respectively formed on both sides of the principal surface 21, a plurality of first and second lead-out electrodes are provided to radially extend from the first and second exciting electrodes, and first and second arcuate electrodes are formed to respectively connect the first and second lead-out electrodes with each other. The second lead-out electrode is then disposed at a position that is not overlapped with a projection area of the first lead-out electrode, and the second arcuate electrode is formed at a position that is not overlapped with a projection area of the first arcuate electrode. |
