PROBLEM TO BE SOLVED: To provide a highly reflective coating material for a fluorescent lamp reflector plate which can produce a reflector plate capable of improving the efficiency of a lighting instrument, and a coated metal plate. SOLUTION: The coating material comprises, based on the total solid contents, (1) 5-60 mass% of titania as a white pigment, and (2) 0.10-10 mass% of a fluorescent pigment having an emission spectrum peak at 480-620 nm and a fluorescent pigment having an excitation spectrum peak at 420-450 nm and emitting light of a wavelength with visibility higher than mercurial line, and is characterized by comprising 0.20-20 mass% in the total of these fluorescent pigments. A highly reflective coated metal plate for a fluorescent lamp obtained by applying the coating material on a metal plate, exhibits a high reflectance at a vicinity of 555 nm which is a peak of visibility of human eyes.
