Title:
液滴吐出ヘッド及び液滴吐出装置
Document Type and Number:
Japanese Patent JP4557019
Kind Code:
B2
Abstract:
A piezoelectric actuator includes upper and lower constant electric potential electrodes. The upper constant electric potential electrodes are connected to a first-common conducting section extending in a predetermined direction, both ends of the first-common conducting section are connected to second-common conducting sections, and thus a first electrode assembly is formed. Both ends of the lower constant electric potential electrodes extending in the predetermined direction are connected to third-common conducting sections, and thus a second electrode assembly is constructed. A flexible wiring board stacked on the piezoelectric actuator has a first-connecting land extending in the predetermined direction and to which one of the first and second electrode assemblies having a smaller voltage drop when a predetermined current is applied is connected, and second-connecting lands to which the other is connected and which are arranged on both end sides of the first-connecting land.
