Abstract:
1. A liquid ejecting head module comprising: a plurality of unit heads, where each unit head has a nozzle surface where a nozzle for ejecting a liquid is formed, a liquid flow path communicating with the nozzle, and a pressure generator creating a change in the pressure of the liquid in the liquid flow path, and ejects the liquid in the liquid flow path from the nozzle by driving the pressure generator; a fixation member in which each unit head is fixed to one fixation surface and the other fixation surface, respectively; a drive substrate which is located on a side of the fixation member opposite to a nozzle surface side of each unit head; and a plurality of wiring members which individually electrically connect the pressure generator of each unit head with the drive substrate, wherein each unit head has a first portion having the nozzle surface, and a second portion which is positioned on an opposite side to the nozzle surface of the first portion, has a contact portion which is in contact with the fixation member when fixed, and accommodates a portion of one of the plurality of wiring members, the contact portion of the second portion is formed at a position closer to a surface of an opposite side to a fixation member side than a side surface of the first portion on the fixation member side, the first portion is positioned further on a liquid ejecting side than the fixation member with the contact portion of the second portion fixed to the fixation member, and each wiring member whose one end portion is connected to the pressure generator is drawn through the second member, from a position close to a surface of the opposite side to the contact portion of the second member to an opposite side to the nozzle surface, and the other end portion of each wiring member is connected to the drive substrate.
