Claim:
1. A composite element chip, comprising: a substrate; and a light emitting element array including a plurality of semiconductor thin-films disposed on the substrate and arranged in a predetermined direction which defines a first direction, each semiconductor thin-film of the plurality of semiconductor thin-films including a plurality of light emitting portions which are arranged so that adjacent light emitting portions are displaced from each other by a predetermined distance in a second direction which is perpendicular to the first direction, the plurality of light emitting portions being arranged along an imaginary line, wherein the plurality of light emitting portions are arranged in a direction inclined with respect to the first direction, wherein each semiconductor thin-film of the plurality of semiconductor thin-films has a first end that is parallel to the second direction; and a second end that extends along a pattern in which the plurality of light emitting portions are arranged and is parallel to the imaginary line, and wherein the first ends of adjacent semiconductor thin films face one another and are displaced from each other in the second direction.
