Zusammenfassung:	To promptly heat fuel in a fuel chamber part in a fuel supply device that heats fuel to be supplied to an injector.SOLUTION: A fuel supply device includes: an injector 40 that supplies fuel to be burned in a fuel chamber of an engine; a fuel chamber part 50 that is connected to an upstream side of the injector 40 and stores fuel to be supplied to the injector 40; and a first heater part 62 disposed in the fuel chamber part 50 and heating the fuel stored in the fuel chamber part 50. A fuel feed passage for feeding the fuel into the fuel chamber part 50 is connected to the fuel chamber part 50. The fuel feed passage includes a second heater part 55 that heats the fuel in a flow passage of the fuel feed passage.SELECTED DRAWING: Figure 5 【課題】インジェクタに供給する燃料を加熱する燃料供給装置において、燃料チャンバ部内の燃料を素早く加熱する。【解決手段】エンジンの燃料室内で燃焼する燃料を供給するインジェクタ４０と、前記インジェクタ４０の上流側に接続され、前記インジェクタ４０に供給する燃料を溜める燃料チャンバ部５０と、前記燃料チャンバ部５０内に配置され、前記燃料チャンバ部５０内に溜めた燃料を加熱する第一ヒータ部６２と、を備え、前記燃料チャンバ部５０には、前記燃料を前記燃料チャンバ部５０内に送る燃料フィード経路が接続され、前記燃料フィード経路には、前記燃料フィード経路の流路内の燃料を加熱する第二ヒータ部５５が備えられている。【選択図】図５
