Abstract:
A method for manufacturing a liquid ejection head includes: a step of preparing a substrate having a first surface on which energy generation elements and a first layer are provided; and a step of forming a supply port by etching the substrate with an etching liquid or an etching gas from a second surface which is a surface opposite to the first surface so as to enable the etching liquid or the etching gas to reach the first layer, and the first layer is divided by a region which is located between a portion of the first layer covering the energy generation elements and a portion of the first layer to which the etching liquid or the etching gas is reached.

Claim (Index 9):
The method for manufacturing a liquid ejection head according to  claim 6 , further comprising: a step of forming a sacrifice layer on the first surface of the substrate before the step of forming the supply port, wherein the sacrifice layer has an etching rate higher than that of the substrate, the first layer is provided on the sacrifice layer, and the second layer is located at a position lower than that of the first layer on the sacrifice layer.
