A light emitting device includes three or more light emitting elements, and a package that includes a base having a mounting face on which the three or more light emitting elements are disposed and a lateral wall part disposed around the light emitting elements and having a light transmitting incident face. The three or more light emitting elements include a first light emitting element that emits first light having an emission peak at a first wavelength along a first optical axis, a second light emitting element that emits second light having an emission peak at a second wavelength along a second optical axis, and a third light emitting element that emits third light having an emission peak at a third wavelength along a third optical axis. An angle formed by the first optical axis and the second optical axis in a top view is 3° to 45°. As the first light and the second light respectively travel along the first optical axis and the second optical axis, a first interval between the first optical axis and the second optical axis increases. The exiting first, second, and third lights are incident on the incident face.
