To efficiently cool a plurality of heat generation parts.SOLUTION: In a circulation passage 500 for temperature-regulation liquid 510, the liquid is pumped up from a temperature-regulation liquid tank 501 by a liquid feeding pump 502, distributed through a cooler 511 from a temperature-regulation liquid supply manifold 505 to heads 100, passed through temperature-regulation liquid passages 130 of the heads 100 to cool the heads 100, passed through the heads 100 to cool head driving parts (a head driving substrate 160 and a head driving IC 161), thereafter collected in a temperature-regulation liquid collection manifold 506, and returned to the temperature-regulation liquid tank 501. A frame member 120 of a head member 110, the head driving parts (the head driving substrate 160 and the head driving IC 161) in this order, i.e. in an ascending order of heat generation amount, when the cooler 511 is set as a starting point, are heat-connected to the circulation passage 500.SELECTED DRAWING: Figure 6 【課題】複数の発熱部を効率的に冷却する。【解決手段】温調液タンク５０１から送液ポンプ５０２で汲み上げられ、冷却器５１１を通り、温調液供給マニホールド５０５から各ヘッド１００に分配され、各ヘッド１００の温調液流路１３０を通ることで各ヘッド１００を冷却し、各ヘッド１００を通過した後、ヘッド駆動部（ヘッド駆動基板１６０、ヘッド駆動ＩＣ１６１）を冷却し、その後、温調液回収マニホール温調液回収マニホールド５０６にて回収され、温調液タンク５０１に戻る温調液５１０の循環経路５００において、冷却器５１１を起点とするとき、相対的に発熱量の少ない順、すなわち、ヘッド１１０のフレーム部材１２０、ヘッド駆動部（ヘッド駆動基板１６０、ヘッド駆動ＩＣ１６１）の順に循環経路５００と熱結合している。【選択図】図６
