Liquid discharging head, method of producing the same and printing apparatus

A method of producing a liquid discharging head, the method comprising:

• forming, in each of a plurality of plates including a first plate and a second plate, a plurality of hollows which constructs a plurality of individual channels each including a nozzle and a pressure chamber communicated with the nozzle;
• forming a groove in an adhesion surface, of the first plate, to which the second plate is to be adhered via an adhesive, and in which the plurality of hollows is opened;
• and
• forming a channel member in which the plurality of individual channels is formed by stacking the plurality of plates in the first direction and adhering the plurality of plates to each other via the adhesive, after the forming of the plurality of hollows and the forming of the groove,
• wherein in the adhesion surface, the plurality of hollows is arranged side by side in a second direction orthogonal to the first direction;
• and
• the groove formed in the forming of the groove is three or more grooves between two of the plurality of hollows adjacent to each other in the second direction, each of the three or more grooves extending in a third direction which is orthogonal to the first direction and which crosses the second direction.
