PROBLEM TO BE SOLVED: To make it possible to position a channel unit of a liquid droplet discharge head and an actuator unit with high accuracy.SOLUTION: In a liquid droplet discharge head which comprises a channel unit which joints a nozzle plate where nozzles for discharging liquid droplets are formed, a channel plate where liquid chambers that communicate with the nozzles are formed and a wall surface member that forms a part of wall surfaces of the liquid chambers, and an actuator unit which comprises actuator members that give pressure change of the liquid chambers formed in the channel unit, a first mark for positioning in connection with the channel unit is formed in the surface of the side of jointing with the channel unit in the actuator unit, a second mark for positioning in connection with the actuator unit is formed in the surface of the side in which the nozzles of the nozzle plate open outside in the channel unit, and the distance between the first mark and the second mark in the liquid droplet discharging direction is the thickness of the channel unit. |
