Document Type and Number:
Japanese Patent JP2913675
Kind Code:
B2
Abstract:
PURPOSE:To ensure easy connection of a substrate and an electrode of each piezoelectric element piece by providing a reference mark for lamination registration to a side of each piezoelectric element. CONSTITUTION:A piezoelectric element Q is integrally formed by laminating and bonding piezoelectric element piece q1 to qn and a substrate (r) on a rough ring having a specified thickness. In this case, a reference mark (m) for lamination registration is provided to a side of each of piezoelectric element pieces q1 to qn. A side section of an insulation side and that of an electrode side are made to align up and down alternatively by alignment of the reference mark (m) for lamination registration in vertical direction. Thereby, it is possible to laminate all the piezoelectric pieces very readily.
