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 1):
A method for manufacturing a liquid ejection head which includes:\n a substrate in which a supply port supplying a liquid is penetrated, energy generation elements each of which generates energy ejecting the liquid, a first layer covering the energy generation elements, and an ejection port member in which ejection ports each of which ejects the liquid are formed, the energy generation elements, the first layer, and the ejection port member being provided on a first surface of the substrate, the method comprising: a step of preparing the substrate having the first layer on which the energy generation element and the first layer are provided; and a step of forming the 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, wherein the first layer is divided by at least one region which is located between a portion of the first layer covering the energy generation element and a portion of the first layer to which the etching liquid or the etching gas is reached.
