发明名称 PIEZOELECTRIC DEVICE
摘要 <P>PROBLEM TO BE SOLVED: To provide a piezoelectric device that takes a measure for preventing a short-circuit due to a runoff of a conductive adhesive applied to an electrode pad. <P>SOLUTION: A piezoelectric device (50) includes: a piezoelectric vibration piece (100), a package (PKG) and an adhesive agent (25). The piezoelectric vibration piece (100) includes: a base (23); a pair of vibration arms (21) that extends from the base in a specified direction; a pair of support arms (22) that extends from the base in a specified direction at the outside of the both of the pair of the vibration arms; a pair of joints (35) that is disposed at the pair of the support arms. The package (PKG) includes: a bottom surface (BT) that houses the piezoelectric vibration piece; a side surface (57) that surrounds the bottom surface; and a pair of electrode pads (55) that corresponds to the pair of the joints and that is formed on the bottom surface. The adhesive agent (25) bonds the pair of the electrode pads and the pair of the joints, respectively. In the piezoelectric device, a position of one of the electrode pads to which the adhesive agent is applied and a position of the other electrode pad are displaced from each other in a prescribed direction. <P>COPYRIGHT: (C)2012,JPO&INPIT
