PROBLEM TO BE SOLVED: To provide a polyarylketone film showing outstanding heat resistance and molding properties, a method for manufacturing this film and a base material for a polyarylketone illuminating equipment which shows lightweight properties, high heat resistance, high heat dissipation and excellent in usability. SOLUTION: This polyarylketone film for molding shows a peak fusion temperature of 300°C or higher and a glass transition temperature of 150°C or higher measured by a differential scanning calorimeter during programming a temperature and that the relationship between a quantity of crystalline fusion heatΔHm and a quantity of crystallization heatΔHcc generated by crystallization during programming a temperature, satisfies formulae (I) and (II). Also a reflector for illuminating equipment which has a reflective material on a reflective base material composed of the polyarylketone film, is provided.ΔHm>5 cal/g...(I)ΔHcc>5 cal/g...(II).
