To prevent the occurrence of carbon deposit in an injection nozzle part by suppressing the increase of temperature at the tip part of the nozzle body (the valve seat) of an electromagnetic type fuel injection valve and shortening a time in which the tip part is brought into a high temperature state.

Since it is noticed that when the temperature of an injection hole 10 is decreased, a carbon deposit does not occur and the heat of the tip part of a nozzle body 5 is discharged to the low temperature part thereof. A fuel injection nozzle 10 is formed and a heat transmission protector 22 is provided to bring the surface 5A on the combustion chamber side of the nozzle body 5 having a fuel passage 11 communicated with the injection nozzle 10 and the low temperature side of the nozzle body 5 into heat contact with each other.
