An ink-jet recording head includes an actuator and a nozzle guide. The actuator ejects ink through a plurality of nozzle apertures. Wiring substrate is connected to the actuator at a connection portion and transmits drive signals to the actuator through the connection portion to drive the actuator to eject ink. The nozzle guide covers an outer periphery of the actuator while exposing the nozzle apertures. The nozzle guide also covers the connection portion between the actuator and the wiring substrate so as to be out of physical contact with ends of the connection portion. The nozzle guide includes a positioning portion used to position nozzle guide with respect to the actuator during assembly. A manifold is connected to the actuator and supplies the ink to the actuator. Seal agent fills areas between the actuator and the nozzle guide, between the wiring substrate and the actuator, between the nozzle guide and the actuator, and between the actuator and the manifold. The seal agent covers the connection portion between the actuator and the wiring substrate, supports the wiring substrate in between the nozzle guide and the manifold, and surrounds the entire outer peripheral surface of the actuator.
