A vehicle drawing device draws a figure on a road surface with a light. When a luminance of the figure is assumed as a road surface drawing luminance, and a luminance in a surrounding environment of a driving vehicle is assumed as a background luminance, the light is irradiated such that a luminance contrast calculated by the road surface drawing luminance and the background luminance is 0.2 or more, and an angle formed by an inclination direction at a tip end of the figure with respect to a light irradiation direction is less than 120 degrees.
