A piezoelectric vibration element includes a piezoelectric piece, a pair of excitation electrodes, and a pair of extraction electrodes. The piezoelectric piece has a rectangular shape with long sides and short sides and a first principal surface and a second principal surface. The piezoelectric piece includes a mesa portion thicker than a peripheral portion at least on the first principal surface. The excitation electrode is larger than an area of the mesa portion and covers the mesa portion on the principal surface where the mesa portion is formed. The excitation electrode has a center away from a center of the piezoelectric piece toward another short side by a first distance. The mesa portion has a center away from the center of the piezoelectric piece to the other short side by a second distance. The second distance is different from the first distance.
