PROBLEM TO BE SOLVED: To securely prevent foreign matter from flowing out onto the downstream side in the direction of fuel flow from a cylindrical part (a filter main body) 33 of a porous filter 31 of a fuel filter 7 and to prevent clogging of the porous filter 31 securely by attracting foreign matter caught in the fuel filter 7 and foreign matter remaining near the fuel filter 7 to a specific section by magnetic force of a magnet 32. SOLUTION: Foreign matter before reaching many minute holes 36 or foreign matter caught once on an inner peripheral side of the porous filter 31 is attracted onto one end face (the specific section) of the magnet 32 by magnetic force of the magnet 32. Since foreign matter included in fuel flowing into the inside of an injector is removed by the fuel filter 7 by providing the fuel filter 7 in an inlet port 22 of the injector, a ratio of foreign matter in fuel flowing into an oil storage chamber and a control chamber provided on the downstream side in the direction of fuel flow more than the fuel filter 7 is reduced.
