1. A light-emitting element to be mounted on a substrate on which a pair of a first connection electrode and a second connection electrode are formed, the light-emitting element comprising:
a light-emitting portion including a first main surface that emits light and a second main surface on an opposite side to the first main surface; and
a first terminal electrode and a second terminal electrode, provided on a second main surface side of the light-emitting portion,
the first terminal electrode including a first cavity portion at a position overlapping the first connection electrode in planar view when the first terminal electrode is brought into contact with the first connection electrode, and joined with the first connection electrode by a laser beam irradiated from the light-emitting portion side, and
the second terminal electrode including a second cavity portion at a position overlapping the second connection electrode in planar view when the second terminal electrode is brought into contact with the second connection electrode, and joined with the second connection electrode by the laser beam.
