Abstract
Abstract A photoelectric conversion device is provided with plural photoelectric conversion cells and signal lines for activating said photoelectric conversion cells. The signal line is composed of plural lines formed in plural layers. The plural lines are electrically connected to every unit composed of a desired number, at least equal to two, of photoelectric conversion cells.
