There is provided a method of manufacturing a glass plate with a light-transmissive colored film using a coating solution including a metal salt and a metal alkoxide, the light-transmissive colored film having a coloring effect due to a metal oxide which will not be impaired even if the amount of the added metal alkoxide is increased, and being highly resistant to wear and chemicals. A method of manufacturing a glass plate with a light-transmissive colored film comprises the steps of hydrolyzing and polymerizing a metal alkoxide to form a hydrolyzed polymeric product, aging the hydrolyzed polymeric product to achieve a weight-average molecular weight no less than 3000 based on polystyrene, preparing a coating solution including the hydrolyzed polymeric product, a metal salt as a coloring component, and a solvent, coating the coating solution on a surface of a glass plate, preliminarily firing the glass plate to convert the hydrolyzed polymeric product into a porous gel, and firing the glass plate to vitrify the porous gel and thermally decompose the metal salt into an oxide.
