Abstract
PURPOSE: To improve strength and to reduce cost by forming a metal for an internal electrode of an ultrasonic oscillator to a two-dimensional net shape and forming said metal to have ≤10μm periods or intervals and ≥3μm average thickness.
CONSTITUTION: Piezo-electric ceramics consisting of multiple layers is formed by laminating piezo-electric ceramics 4, the internal electrode 7 and an external electrode 6 to a laminar state and calcining the same and is connected to an earth electrode 11 and a signal side electrode 12, respectively. The periods or intervals of the metal of the electrode 7 formed to the net shape are specified to ≤10μm and the average thickness thereof is set to ≥3μm. The electrode 7 is formed like a net and the area of the ceramics 4 occupying in the entire area of the internal electrode is increased to improve the strength and to decrease the use amt. of the platinum occupying ≥90% of the raw material cost of the electrode 7. The raw material cost is, therefore, reduced while the mechanical strength is improved.
