Abstract
Provided is a first flow path substrate where a first flow path out of a liquid flow path is formed, a second flow path substrate where a second flow path which communicates with the first flow path is formed, and a third flow path substrate where a pressure chamber which communicates with the second flow path is formed. The second flow path substrate has a first surface which is bonded to oppose the third flow path substrate and a second surface which is bonded to oppose the first flow path substrate; the first surface of the second flow path substrate is bonded with the third flow path substrate via a film of paraxylene; and the second surface of the second flow path substrate is bonded by an adhesive of a material which is different from that of the film of paraxylene.
