Method for manufacturing liquid discharge head

A method for manufacturing a liquid discharge head, the liquid discharge head including:

• a substrate which is provided on a surface with a first energy generating part and a second energy generating part for generating energy to be utilized for discharging a liquid;
• a first discharge port through which a liquid is discharged, said first discharge port being provided corresponding to said first energy generating part so as to face said surface;
• a second discharge port through which a liquid is discharged, said second discharge port being provided corresponding to said second energy generating part so as to face said surface;
• a first wall member which has a wall of a first flow path for a liquid which communicates with said first discharge port;
• and a second wall member which has a wall of a second flow path for a liquid which communicates said second discharge port, wherein a distance between said second energy generating part and said second discharge port is greater than a distance between said first energy generating part and said first discharge port,
• the method comprising:
• providing on said substrate a first mold for said first flow path and a second mold for said second flow path, said first mold corresponding to said first energy generating part, said second mold corresponding to said second energy generating part;
• providing a first cover layer to serve as said first wall member so as to cover at least said first mold;
• forming said first discharge port and a first portion of said second wall member by removing a part of said first cover layer;
• providing a second cover layer to serve as a second portion of said second wall member so as to cover said first portion and said second mold, and so that a distance between said surface and an upper surface of said second cover layer is longer than a distance between said surface and said first discharge port;
• forming said second discharge port by removing a part of a portion constituting said upper surface of said second cover layer;
• and
• forming said first flow path by removing said first mold and forming said second flow path by removing said second mold.
