Document Type and Number:
Japanese Patent JP2015136595
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an ultrasonic vibration device which has a constitution in which a discharge phenomenon from a metallic electrode plate of a piezoelectric substance unit to a metal case body is prevented, and whose diameter is made narrower than that of the prior art.SOLUTION: An ultrasonic vibration device 2 comprises: a lamination vibrator on which a plurality of piezoelectric substances 61 and a plurality of electrode plates 62a, 63a are laminated; two insulation plates 42, 43 which are arranged on both ends of the lamination vibrator; a metal case 50 which stores the lamination vibrator and the two insulation plates 42, 43; an insulation processing unit 71 which insulates the exposed part of the plurality of electrode plates 62a, 63a from the metal case 50; and an opening which is formed in the metal case 50, and introduces the insulation material forming the insulation processing unit 71 into the metal case 50 after the lamination vibrator and the two insulation plates 42, 43 are stored and fixed in the metal case 50.
