Abstract
A light-emitting element array chip includes: a first light-emitting element array that includes a first light-emitting element including a first substrate, a light-emitting element layer formed on the first substrate, and a first cathode electrode electrically connected to the light-emitting element layer; and a second light-emitting element array that includes a second light-emitting element including a second substrate, a non-p-type lower reflector formed on the second substrate, and a second cathode electrode electrically connected to the non-p-type lower reflector, in which the first light-emitting element array is provided on an emission surface side of the second light-emitting element array.
