LIQUID EJECTION HEAD AND MANUFACTURING METHOD THEREFOR

To provide a liquid ejection head that realizes a higher speed and higher image quality.SOLUTION: A liquid ejection head 20 has a substrate 1 and a plurality of ejection port forming members 11, 12 provided on the substrate 1. Each of the ejection port forming members 11, 12 has a channel 5, 6 formed between the substrate 1 and the member and communicating with an ejection port 8 for ejecting a liquid. The plurality of ejection port forming members 11, 12 are formed so as to differ from each other in thickness and so that the channels 5, 6 differ from each other in height.SELECTED DRAWING: Figure 1 【課題】高速化と高画質化を実現する液体吐出ヘッドを提供する。【解決手段】液体吐出ヘッド２０は、基板１と、基板１に設けられた複数の吐出口形成部材１１，１２とを有し、各吐出口形成部材１１，１２は、基板１との間に形成され、液体を吐出する吐出口８に連通する流路５，６を有している。複数の吐出口形成部材１１，１２は、厚みが互いに異なるとともに、流路５，６の高さが互いに異なるように形成されている。【選択図】図１
