PROBLEM TO BE SOLVED: To provide a fuel injection valve of simple assembly reducing noise to outside by reducing transmission of operation noise. SOLUTION: An obstacle 7A provided with a restriction part 7a is integrally constituted with an adjuster 7 for adjusting spring force of a spring 6 energizing a needle valve 11 in a close direction. The obstacle 7A is press fitted in a valve main body to make an outer circumference of the obstacle 7A contact with an inner circumference of a valve main body and to increase rigidity, thereby blocking the transmission of operation noise by the obstacle 7A.
