Flow path structure, liquid ejecting apparatus, liquid ejecting head, and method of manufacturing flow path structure

A method of manufacturing a flow path structure that includes a flow path defined by a first flow path member having a film member having a film and a resin member made of a resin and having a recessed portion, and a second flow path member laminated on the first flow path member, the method comprising:

• creating the film member by forming unevenness corresponding to the recessed portion in the film by bending the film while heating the film;
• creating the first flow path member in which the film member and the resin member are integrally molded so that the unevenness and the recessed portion correspond to each other, by fixing the film member to a mold and injecting the resin into the mold to perform molding;
• and
• adhering the first flow path member and the second flow path member to each other so that the film member and the second flow path member define at least a portion of the flow path in a region overlapping the recessed portion in a laminating direction of the first flow path member and the second flow path member.
