INKJET HEAD AND APPLYING DEVICE HAVING INKJET HEAD

摘要

PROBLEM TO BE SOLVED: To improve quality of a printed material by improving a reduction of an adequate amount of ink from an ink channel at an end portion of a head unit due to crosstalk even using a simple drive circuit.

SOLUTION: This inkjet head is so constituted that an absolute value of a difference between a length of a first piezoelectric material and a length of a second piezoelectric material in a laminating direction at the sidewall of each of two ink channels that are respectively placed at both ends in an arrangement direction of a plurality of ink channels for ejecting ink is smaller than that of the ink channel positioned at a central portion.
