Abstract
A piezoelectric vibrator, an oscillator, an electronic device and a ratio timepiece are provided which are capable of increasing a capacitance C0 while achieving miniaturization and cost reduction. The piezoelectric vibrator includes a base substrate, a lid substrate, a piezoelectric vibrating reed on which an excitation electrode is formed, and external electrodes. An electrode pattern for capacitance adjustment, which extends along a routing electrode, is provided extending from a routing electrode.
