To provide a fuel injection valve formed so that the periphery of an injection hole can be surrounded by a wall surface by injecting a spray with a penetration force smaller than that of a single hole valve.
This cylinder direct injection type internal combustion engine is formed such that the injection hole 5 is formed at the bottom part of a recessed part 4 formed in the body of the fuel injection valve 1 so that a spray fuel can be prevented from adhering to the wall surface to suppress the introduction of peripheral air into the spray at a spray root part. By this, the spray is not contracted by the pressing of the flow of the peripheral air even under the conditions of high atmospheric pressure, the spray with low penetration force having a spray angle not influenced by the atmospheric conditions can be formed to prevent wall wet from generating.
