A fuel injection device includes a cylindrical valve housing, a valve needle disposed inside the valve housing and a ceramic heater disposed around the valve housing. The valve housing has a fuel inlet at an end, a first fuel passage, a second fuel passage, a nozzle hole at the other end and a valve seat. The valve needle has a hollow portion connected to the first fuel passage and a plurality of fuel apertures connecting the hollow portion and the second fuel passage, a head portion disposed to be seated on or unseated from the valve seat thereby intermittently injecting fuel through the nozzle hole. The ceramic heater is disposed around the valve housing down stream of the fuel apertures and upstream of the valve seat. Fuel vapor can be discharged upward though the fuel apertures.
