PURPOSE: To reduce a setting space as well as to make up a fuel injection valve into such one as being excellent in a cooling effect, by circulating fuel inside of the body without changing any dimensions in a setting part of the injection valve for the conventional multipoint injection, to an engine.

CONSTITUTION: Fuel having passed through the inside of a fuel inflow passage 128 of a spring adjuster 103 is flowing into the inside of an injection valve. And, it passes through a clearance in a spring 105, entering each peripheral surface of a fixed iron core 102 and a movable iron core 107 and a iron core circumferential passage 103 from plural slits 129, passing each of circumferential passages 121, 122 and 123 of a coil 104 and further passing a fuel outflow passage 125 from a hole 124 installed in the fixed iron core 102, and it is returning as passing a delivery pipe, supplying the injection valve with fuel, from a groove 127 installed on the circumference of a fuel connector 126.
