Abstract
In an image pickup portion of a frame transfer CCD image sensor, a constitution that inhibits color mixing from occurring between light-sensitive pixels adjacent along a vertical CCD shift register channel is provided. A protrusion extending on the channel is formed at a clock wiring formed on a channel stop of the vertical CCD shift register with an wiring layer having the light-shielding property. When the protrusion portion is disposed at a boundary of light-sensitive pixels in the channel, a non-light-shielding portion generated at the boundary can be suppressed. The protrusions are disposed so as to alternately protrude from the clock wirings on both sides of the channel.
