Abstract
A fuel injection valve includes: a nozzle body portion; a valve body; and a valve seat. The valve body and the valve seat define a fuel space which is shielded from the fuel injection hole and is supplied with the fuel in a case where the valve body is in a state of being seated on a valve seat portion. The fuel space includes at least a space between a side surface of the valve body and a surface forming an accommodation space of the valve seat. The valve body and the valve seat are configured to cause the fuel space and the fuel injection bole to communicate with each other in a case where the valve body is in a state of being separated from the valve seat portion. A light irradiation portion is disposed at a position where the fuel space is irradiated with transmitted light.
