An image sensor of present invention comprising a plurality of pixels arranged in a matrix and having pixels where at least three kinds of color filters are disposed, color pixels where the color filters are disposed and monochrome pixels where no color filter is disposed are provided, the sum total of the monochrome pixels is larger than the sum total of the color pixels, and when pixels including a predetermined number of color pixels for each kind of color filter constitute one group, the color pixels or the pixels of the groups are dispersedly disposed with the monochrome pixels in between. Compared to the image sensors in which only color pixels where color filters are disposed are arranged and the conventional image sensors in which the sum total of the monochrome pixels is equal to or smaller than the sum total of the color pixels, the effective sensitivity of the image sensor can be improved, so that photographing with high sensitivity can be performed and a beautiful image with an excellent (high) S/N ratio can be obtained.
