Document Type and Number:
Japanese Patent JP5197178
Kind Code:
B2
Abstract:
An ink jet print head substrate is provided which can prevent voltage drop variations during driving, no matter in what way the ejection energy generation elements are driven, and which can also apply a stable energy to the ejection energy generation elements at all times. The ink jet print head substrate of this invention has a plurality of kinds of ejection energy generation elements to generate different magnitudes of ink ejection energy and wiring portions. The print head substrate also has a plurality of wiring layers arranged to at least partly overlap one another. The wiring portions connected to the different kinds of ejection energy generation elements are provided at least partly in different wiring portions.
