<P>PROBLEM TO BE SOLVED: To provide a piezoelectric device capable of desirable detection by preventing deformations of lead plates holding a piezoelectric oscillating reed when an impact is added to the piezoelectric device and preventing reductions in detection sensitivity due to lead plate deformations. <P>SOLUTION: In a gyroscope sensor 100, which is the piezoelectric device, a gyroscope oscillating reed 10; a plurality of the lead plates 15; and a supporting substrate 18 are housed in a package 20, and a lid 21 is fastened to a fastening surface of the package 20. Lead plate reinforcing parts 16 in which parts of the supporting substrate 18 are extended to a window overhang part 25 of the supporting substrate 18 correspondingly to the leads plate 15 are joined to the lead plates 15. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
