Abstract

The invention is to reduce a color mixing resulting from influences of adjacent pixels. The invention provides a solid-state image pickup apparatus including plural pixels each including a PN junction area constituting a photoelectric conversion area, a floating diffusion area for holding a charge outputted from the PN junction area, an amplifying transistor for amplifying the charge in the floating diffusion area, and a wiring for connecting at least the floating diffusion area, a gate electrode of the amplifying transistor and a resetting MOS transistor, and a signal output line for outputting signals from the amplifying transistors, the apparatus including shield lines between the wiring of one pixel or the floating diffusion area and the wiring of one pixel and the signal output line of another adjacent pixel.
