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 for discharge through the liquid supply conduit. Liquid that passes through the head flows to the liquid discharge conduit. The radiator includes a flow path through which a coolant flows. The coolant is different from the liquid supplied to the head for discharge. The first wiring board is between the head and the radiator and has a connector connected to a wiring extending through an inner space of the radiator. The second wiring board is between the head main body and the first wiring board, and includes, thereon, a driving control element. The heat conductive member extends between the head and the radiator, and is in thermal contact with the radiator.
