Abstract: A liquid discharge head includes a head, a liquid supply conduit, a liquid discharge conduit, a radiator, first and second wiring boards, and a heat conductive member. Liquid is supplied to the head through the liquid supply conduit. Liquid that passed the head flows through the liquid discharge conduit. The radiator includes a flow path through which liquid from the liquid discharge conduit flows. The first wiring board is between the head and the radiator, and has a connector connected to a wiring extending through an interior of the radiator. The second wiring board is disposed between the head main body and the first wiring board, and includes, thereon, a driving control element configured to control liquid discharge from the discharge holes. The heat conductive member extends between the head and the radiator, and is in thermal contact with the radiator.
