Abstract
A light-emitting element package includes plural substrates and plural light-emitting elements disposed on each of the substrates. The light-emitting elements are arranged on each substrate so that an arrangement of the light-emitting elements on each substrate becomes same in an arrangement state in which the substrates are arranged with a regular pitch along a first direction and a second direction which are directions perpendicular to the substrate. The light-emitting elements are arranged on each substrate so that a pitch of the light-emitting elements on each substrate is equal to a pitch of the light-emitting elements between the neighboring substrates in the arrangement state of the substrates.
