A semiconductor chip provided with a light-sensitive device portion having a plurality of light-sensitive devices arranged linearly in the longer side direction, and a read-out circuit cell portion having read-out circuit cells arranged linearly in the longer side direction, each corresponding to one light-sensitive device, has a common signal line for a signal output and a common signal line for a reference output, that are a pair of signal lines, formed in a conductor portion lying between the read-out circuit cell portion and a logic circuit portion in such a way that they extend in the longer side direction while exchanging their positions in the shorter side direction every predetermined length.
