<p>A fuel injection valve which ensures improved uniformity of a swirl flow in a circumferential direction. It includes: a valve element (6) provided movably; a nozzle body (2) with an opening downstream, including a valve seat face (3) for the valve element (6) to rest on in a valve closed state; a swirling path (21a-21c) communicating with the opening (5) of the nozzle body (2), located downstream of the opening (5); a swirling chamber (22a-22c) located downstream of the swirling path (21a-21c), in which fuel is swirled and given a swirling force; and a fuel injection hole (23a-23c) formed at the bottom of the swirling chamber (22a-22c) to inject fuel outward. The swirling chamber (22a-22c) has an inner wall surface which makes a spiral curve. The swirling chamber (22a-22c) and the fuel injection hole (23a-23c) are formed so that the center of a base circle for the spiral curve coincides with the center of the fuel injection hole (23a-23c).</p>
