Abstract
A fuel injection valve includes a body that includes an injection hole through which fuel is injected, and a valve element that opens or closes the injection hole. The body includes a metallic base material configured to form the injection hole, a corrosion-resistant layer covering a surface of at least a part of the base material that forms the injection hole and being made of a less corrosive material than the base material, and a sacrificial corrosion layer located between the base material and the corrosion-resistant layer and made of a more corrosive material than the corrosion-resistant layer.
