<P>PROBLEM TO BE SOLVED: To provide a highly reliable piezoelectric oscillation device by improving impact resistance. <P>SOLUTION: An elastic support having a buffer function in a three-dimensional direction is bonded to a base. On the holding part of the elastic support, a piezoelectric vibration plate is loaded in a flat state in the state that the main surface of both short sides of it is held. A conductive bonding material S is applied to the diagonal position of both short sides of the piezoelectric vibration plate, and is conductively bonded with the elastic support. Relative to the short side length W of the piezoelectric vibration plate, the length Ws of the conductive bonding material is set to the length of about 30%. <P>COPYRIGHT: (C)2010,JPO&INPIT |
