Abstract
A method of arraying self-scanning light-emitting element array chips is provided, in which it is possible to remove defective chips completely. A plurality of self-scanning light-emitting array chips in a zigzag manner on a substrate, each chip being rectangular and comprising an array of light-emitting elements arrayed in a line facing to one end of the chip and a plurality of bonding pads provided on the other end of the chip. The plurality of chips are arrayed in such a manner that one ends of neighboring chips are arranged without overlapping in an array direction of chips so that an array pitch of chips is constant, and the other ends of the chips are arranged with overlapping in a direction perpendicular to an array direction of chips so that an array pitch of chips is constant.
