Abstract:
1. A solid-state imaging device comprising: a light-receiving portion, which is provided in an imaging area set on a surface of a semiconductor substrate and converts incident light into a signal charge; at least one transfer channel extending in one direction in the imaging area; a group of transfer electrodes, which extend in a direction crossing the transfer channels on the imaging area and to which transfer signals of plural phases are applied so as to transfer the signal charge through the transfer channel; and a group of transfer signal lines, which are provided along a periphery of the imaging area on the semiconductor substrate and connect an input terminal to which a transfer signal is inputted with an end portion of the transfer electrode to which the transfer signal is to be applied, in every transfer signal of each phase, wherein a transfer signal line connected to a transfer electrode having a large surface area on the transfer channel in the group of the transfer electrodes, of the transfer signal lines that constitute the group, has an electrical resistance smaller than that of a transfer signal line connected to a transfer electrode having a small surface area on the transfer channel in the group of the transfer electrodes.
