PIEZOELECTRIC TRANSFORMER |
摘要 |
PROBLEM TO BE SOLVED: To provide a piezoelectric transformer which ensures reliability of electrical connection at a low cost when used in a long period of time and does not lower performance of a piezoelectric transformer regarding a connection method of an electrode terminal of a piezoelectric transformer. SOLUTION: A surface electrode of a piezoelectric transformer 10 is formed in a surface comprising a node of vibration or thereabout in a the longitudinal direction of a piezoelectric ceramic rectangular plate. An electrode terminal 1 is substantially formed of a metallic thin plate having elastic property provided with one en joined to the surface electrode and the other and connected and fixed to a substrate electrode of an insulation substrate. The piezoelectric transformer 10 is arranged on the insulation substrate 12 with the substrate electrode through the electrode terminal 1.
