Zusammenfassung:A light-emitting element and a light-emitting device having low light loss, high luminance, and high light extraction efficiency are provided. The light-emitting element includes: a semiconductor structure layer having a light-emitting layer; a light-transmitting substrate provided on the semiconductor structure layer; a wavelength conversion layer disposed on the light-transmitting substrate; a light-transmitting covering member configured to cover at least a part of a side surface of the light-transmitting substrate and have transparency to light from the light-emitting layer; and a light-shielding member configured to entirely cover surfaces including a surface of the light-transmitting covering member, and including a side surface of the semiconductor structure layer, a side surface of the light-transmitting substrate, and a side surface of the wavelength conversion layer.
