Disclosed is a color linear image sensor having a small line-to-line distance, which comprises signal charge storage sections adjacent to light receiving sections. Signal charges are read by signal charge reading sections from the signal charge storage sections to signal charge transfer sections, and thereby residual images are prevented from being generated. Each of the signal charge reading sections is electrically connected with a portion of the signal charge transfer section which is adjacent to the signal charge reading section, and driving pulses are made common (phi1 (TG)). Alternatively, each of the signal charge storage sections is electrically connected with a portion of the signal charge transfer section which is not adjacent to the signal charge reading section, and driving pulses are made common ((phi2 (ST)). Accordingly, the number of wiring lines (pulse lines) arranged between the light receiving sections of respective colors is reduced by one. Therefore, without greatly increasing a distance (line-to-line distance) between the light receiving sections of three RGB colors, residual images are suppressed.
