The present invention is a charge transfer device that includes: a charge transfer unit 203 that transfers signal charge; a first gate electrode 201 which is formed above the charge transfer unit 203 and controls the transfer; a second gate electrode 202 which is formed, covering an edge of the first gate electrode, above the charge transfer unit 203, and adjacent to the first gate electrode 201; a first wiring portion 208 which is connected to the first gate electrode 201 for applying driving voltage to it; a second wiring portion 209 which is connected to the second gate electrode 202 for applying driving voltage to it. The second wiring portion 209 is formed within an area above the first wiring portion 208 and within an area inward of edges along a length of the first wiring portion 208, or is formed, covering an edge of the first wiring portion 208 with an overlap length which is equal to or shorter than a gate overlap length of the vertical transfer unit 203.
