Liquid discharge head, liquid discharge apparatus, and method of manufacturing liquid discharge head

A method of manufacturing a liquid discharge head, the liquid discharge head including a discharge unit including a plurality of first liquid flow paths;

• a supply unit fixed to the discharge unit, including a plurality of second liquid flow paths, and configured to supply liquid to the discharge unit;
• and a sealing member sandwiched by the discharge unit and the supply unit, the sealing member including a plurality of third flow paths in communication with the plurality of first liquid flow paths and the plurality of second flow liquid paths, and a plurality of flow path arrays, each flow path array including the plurality of third flow paths arranged in a column direction, the manufacturing method comprising:
• a grasping operation including sucking a surface on which the plurality of third flow paths of the sealing member open with a suction head and grasping the sealing member;
• a positioning operation including positioning the sealing member grasped by the suction head relative to the supply unit, so that a contact surface of the supply unit contacts the sealing member;
• and
• a mounting operation of moving the suction head and placing the sealing member on the supply unit.
