<P>PROBLEM TO BE SOLVED: To provide a piezoelectric device capable of suppressing a manufacturing cost by reducing the area of a mounting terminal, and capable of suppressing cracking of a solder. <P>SOLUTION: A piezoelectric device (100) is such piezoelectric device as mounted on a printed board (160) by solder (143). The device includes a piezoelectric vibration piece (130) containing a pair of excitation electrodes (131) on both main surfaces, and a base part (120) which contains a bottom surface consisting of a major side and a minor side, and a pair of mounting terminals (124) which are formed at both ends in the major side direction of the bottom surface, to be conductive to the pair of excitation electrodes respectively and mounted on the printed board. The pair of mounting terminals are formed with a predetermined interval (X3) being closest in the major side direction while not shorting by solder when the piezoelectric device is mounted on the printed board, with a maximum width (Z2) in the minor side direction of the mounting terminal being formed to be a half of a minor side (Z1) or less. <P>COPYRIGHT: (C)2012,JPO&INPIT |
