Abstract: To prevent ejection failure which occurs because openings of nozzles are clogged with fine burrs generated at a parting line (P) of a flow path member (2) formed by molding, provided is a liquid jet head (1) including the flow path member (2) and an actuator portion (3). The flow path member (2) includes a first member (4) and a second member (5) bonded thereto. A flow path (8) and a discharge port (12) communicated to the flow path (8) are formed between the first member (4) and the second member (5). The first and second members (4, 5) each include a parting line formed by molding on a surface thereof. The parting line is not positioned on an inner surface forming the flow path (8), and is positioned on the surface of the first member (4) or the second member (5) other than the inner surface.
