PROBLEM TO BE SOLVED: To provide a fiber-reinforced composite material containing a polyketone fiber, and having excellent impact resistance, fatigue resistance and toughness by improving adhesion between a matrix material and the polyketone fiber.SOLUTION: The polyketone fiber of which 75 mol% of repeating units is 1-oxotrimethylene represented by formula (1) is obtained by attaching a reactant chemically reacting with a carbonyl group of the fiber thereto.
