摘要： A member for an internal combustion engine, such as a piston, a valve and a fuel injection valve. The member includes a substrate. A carbon-based coating film is formed on the substrate to cover at least a part of a region of the substrate to which region fuel for the internal combustion engine is contactable. The carbon-based coating film contains fluorine and has a thickness of 10 μm or less.
