A transmission type color calibration chart includes a transparent substrate and a color bar group formed on the transparent substrate, wherein the color bar group is constituted by color bars of a plurality of colors containing at least a first color and a second color arranged in a pattern in no particular order, coordinate points of the first color are within a region encompassed by the four points (0.351, 0.649), (0.547, 0.453), (0.380, 0.506) and (0.433, 0.464) on an xy chromaticity diagram, coordinate points of the second color are within a region encompassed by the four points (0.125, 0.489), (0.112, 0.229), (0.270, 0.407) and (0.224, 0.242) on an xy chromaticity diagram, and the transmission spectrum of the first color's color bar and the transmission spectrum of the second color's color bar have peak tops that are respectively separated.
