A solid state image device includes a pixel unit including a plurality of pixels arranged in a matrix; an analog-to-digital conversion unit that converts a signal from the pixel unit into a digital signal; a digital circuit unit that processes the digital signal from the analog-to-digital conversion unit; and a wiring that supplies a predetermined voltage to the pixel unit. The wiring includes a first wiring section facing the pixel unit, a second wiring section facing at least one of the analog-to-digital conversion unit and the digital circuit unit, and a third wiring section connected to an electrode pad and connected to an electrode pad and between the second wiring section and the electrode pad, and the width of the second wiring section is smaller than respective widths of the first wiring section and the third wiring section.
