<P>PROBLEM TO BE SOLVED: To provide a piezoelectric device, wherein the cost is reduced by using a simplified piezoelectric vibrating piece packaging device while using a piezoelectric vibrating piece capable of implementing a method for simply adjusting a connecting position of the piezoelectric vibrating piece. <P>SOLUTION: In a piezoelectric device 10, a crystal vibrating piece 11 including exciting electrodes 13a, 13b formed on front and rear principal surfaces 12a and 12b, drawing electrodes 14a, 14b extending from the exciting electrodes, connecting electrodes 16a, 16b extending from the drawing electrodes, and marker electrodes 15a, 15b provided between the exciting electrodes and the connecting electrodes, is connected to PAD electrodes 21a, 21b formed in a package 20. The crystal vibrating piece has light transmissivity at least between the connecting electrodes and the marker electrodes and is connected to the PAD electrodes wherein one side 24a of each of the PAD electrodes, at the side of the exciting electrodes, is arranged between the connecting electrodes and the marker electrodes. <P>COPYRIGHT: (C)2010,JPO&INPIT |
