Abstract:
1. A line head, comprising: a head substrate; a first light emitting element group which is arranged on the head substrate and includes a first light emitting element and a second light emitting element; a first lens which images a light emitted from the first light emitting element group; a second light emitting element group and a third light emitting element group which are spaced apart by a space in a first direction and located more toward one side in a second direction orthogonal to or substantially orthogonal to the first direction than the first light emitting element group on the head substrate; a second lens which images a light emitted from the second light emitting element group; a third lens which images a light emitted from the third light emitting element group; a first wiring which is arranged through the space between the second and the third light emitting element groups on the head substrate and is electrically connected with the first light emitting element; and a second wiring which is arranged through the space between the second and the third light emitting element groups on the head substrate and is electrically connected with the second light emitting element; wherein in a planar view, the first wiring and second wiring pass between the second lens and the third lens and are drawn from the first light emitting element group to a one side area located more toward the one side in the second direction than the second light emitting group and third light emitting element group.
