PROBLEM TO BE SOLVED: To provide a cylinder for an internal combustion engine whose inner circumferential face to be a piston sliding face is subjected to environmentally-friendly plating having hardness tolerable for practical use, and dispensing with finish working such as honing, and to provide an inner circumferential face treatment method by which the cylinder can be obtained. SOLUTION: In the cylinder for an internal combustion engine made of an aluminum alloy, a nickel-phosphorous-boron based electroless plating film (20) is formed on the inner circumferential face (9) to be a piston sliding face.
