Abstract
A light emitting element array includes plural light emitting elements connected in parallel to each other by a wiring connected to a terminal that supplies a current. Each of the light emitting elements is disposed at a position of a predetermined path length along a path of the current flowing from the terminal through the wiring. The plural light emitting elements include, in a mixed form, one or more first light emitting elements each having a non-shielded light emission aperture and one or more second light emitting elements each having a shielded light emission aperture. At least one of the first light emitting elements is disposed at a position of the longest path length. At least one of the second light emitting elements is disposed at a position of the shortest path length.
