A color imaging device includes a semiconductor substrate including a plurality of photoelectric transducers, and a color filter including a plurality of coloring layers provided to associate with the photoelectric transducers of the semiconductor substrate. Each of the coloring layers of the color filter including a side surface that is erected with respect to a surface of the semiconductor substrate, and an inclined surface that is continuous from an end of the side surface located in the opposite side of the semiconductor substrate toward an end portion of the coloring layer located in the opposite side of the semiconductor substrate. The coloring layers are arranged with their side surfaces being in contact with each other without a gap therebetween, and the end portion of the coloring layer has a curved surface shape protruding toward the opposite side of the corresponding photoelectric transducer.
