PROBLEM TO BE SOLVED: To provide a liquid discharge head which inhibits streaks resulting from unevenness of a liquid caused by differences in application time between adjacent dots and enables high density recording.SOLUTION: A liquid discharge head includes: a first discharge port group in which a plurality of discharge ports for discharging one kind of liquid to a recording medium are arranged in a first direction; and a second discharge port group which is provided along the first discharge port group and discharges the one kind of liquid to the recording medium. The first discharge port group is provided at the upstream side relative to the second discharge port group with respect to a relative moving direction in which the recording medium and the liquid discharge head are relatively moved. The plurality of discharge ports included in the first discharge port group are provided in a zigzag manner in the first direction. The liquids discharged from the discharge ports located adjacent to each other in the first direction is brought into contact with each other on the recording medium.SELECTED DRAWING: Figure 11 【課題】隣接ドットとの着弾時間差によって発生する液体の偏りによるスジの抑制と、高密度記録が可能な液体吐出ヘッドとの両立。【解決手段】記録媒体に対して第１の種類の液体を吐出する複数の吐出口が第１の方向に配列された第１の吐出口群と、前記第１の吐出口群に沿って設けられる、記録媒体に対して前記第１の種類の液体を吐出する第２の吐出口群と、を備える液体吐出ヘッドであって、前記第１の吐出口群は前記第２の吐出口群に対して前記記録媒体と前記液体吐出ヘッドの相対移動方向に関する上流側に設けられており、前記第１の吐出口群に含まれる複数の吐出口は、前記第１の方向にジグザグ状に設けられており、前記第１の方向に互いに隣接する吐出口から吐出される液体は記録媒体上で接触する、液体吐出ヘッド。【選択図】図１１
