Zusammenfassung:Deviation free of brightness distribution enables a light emitting element with uniform illumination and a light emitting device using the same to be obtained. The light emitting element with a hexagonal planar shape, has: an n-side semiconductor layer (2n); a p-side semiconductor layer (3p) provided on the n-side semiconductor layer (2n); a plurality of holes (6) that are provided to an area excluding at least three corners (R2, R4, R6) at mutually diagonal positions of the p-side semiconductor layer (3p) in top view, and expose the n-side semiconductor layer (2n); a first p-electrode (4p) provided in contact with the p-side semiconductor layer (3p); second p-electrodes (5p) provided to the at least three corners (R1, R3, R5) on the first p-electrode (4p); and an n-electrode (7n) that is provided on the first p-electrode (4p) and is electrically connected to the n-side semiconductor layer (2n) through the plurality of holes (6). 种无亮度分布的偏差,可得到均匀发光的发光元件及使用发光元件的发光装置。发光元件的平面形状为六边形,具有:n侧半导体层(2n);在n侧半导体层(2n)上设置的p侧
