That the pressure fluctuation in a pressure chamber (19) of a fuel injection valve leads to the diameter extension of a valve body (1) causes the relative movement of a valve sealing face (7) which corresponds to a valve needle (5) and a valve seat (9), thereby the increased friction which can lead to the change of the opening characteristic of the fuel injection valve can occur at the position. In order to solve the problem, a layer (30), the steel friction coefficient of which is relatively increased, is imposed on one of the surfaces (7, 9), thereby the two surfaces (7, 9) are well adhered so as not to do the relative movement when the corresponding pressure fluctuation occurs in the valve body (1). A substitute scheme that a layer which has the corresponding high friction coefficient relatively to the layer which has the same type is respectively imposed on the valve seat (9) and the valve sealing face (7) can also be considered.
