Abstract
A fuel injection valve is a fuel injection valve for injecting fuel to a combustion chamber of an internal combustion engine, which includes a valve body that is lifted by any one of a first lift amount of a maximum valve body lift amount and a second lift amount smaller than the first lift amount. In a case where the maximum valve body lift amount of the valve body is the first lift amount, a flow path area of a seat portion is larger than a sum of flow path areas of all injection holes, and in a case where the maximum valve body lift amount of the valve body is the second lift amount, the flow path area of the seat portion is smaller than the sum of flow path areas of all the injection holes.
