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 8):
The method for manufacturing a liquid ejection head according to  claim 6 , wherein the second layer penetrates the substrate, and the second layer is projected to the supply port.
