description A valve element is movable in a main body for opening and closing the nozzle hole. A pressure control chamber is formed at an end of the valve element and configured to receive high-pressure fuel to bias the valve element so as to close a nozzle hole. A first communication passage communicates the pressure control chamber with a low pressure side. An accommodating chamber is located downstream of the first communication passage and acommodates a valve member. A low-pressure opening is for exhausting fuel from the accommodating chamber. The valve member has a valve portion to control fuel flowing from the pressure control chamber to the low pressure side. The accommodating chamber and the low-pressure opening therebetween has a passage, which defines a throttle portion.
