The present invention provides a fuel injection valve and a production method thereof to shorten the reach distance of sprayed mist. In order to achieve this purpose, the present invention has concavities (301o) formed by press-working in an outer surface of an injection hole formation member (301), and fuel injection holes (301n) formed by liquid jet lasers such as water jet lasers in bottom surfaces (301ob) of the concavities (301o). Preferably, the fuel injection holes (301n) is decreased from an inlet side to an outlet side.
