CRYSTAL DEVICE, MANUFACTURING METHOD OF THE CRYSTAL DEVICE, PIEZOELECTRIC TRANSDUCER, OSCILLATOR, ELECTRONIC APPARATUS, AND ATOMIC CLOCK

摘要

PROBLEM TO BE SOLVED: To provide a crystal device which positions electrode patterns and bumps with high accuracy while reducing manufacturing man hours and a manufacturing method of the crystal device, and to provide a piezoelectric transducer, an oscillator, an electronic apparatus, and an atomic clock.

SOLUTION: A crystal device includes routing electrodes 27 and 28 formed on a base substrate 2 and bumps B for mounting a piezoelectric vibration piece 5 on the routing electrodes 27 and 28. Alignment marks 35 and 36 for positioning the bumps B are formed on the base substrate 2 separately from the routing electrodes 27 and 28.
