Abstract

Provided are a light emitting element and a light emitting device with improved light emission intensity distribution. A light emitting element includes a light-transmissive substrate, an n-type semiconductor layer, a first p-type semiconductor layer, a first p-side electrode, a first n-side electrode, a second p-type semiconductor layer, a second p-side electrode, and a second n-side electrode. A light emitting device includes the light emitting element, and an external connection electrode provided at the light emitting element on a side opposite to the light-transmissive substrate. The external connection electrode includes an n-side external connection electrode connected to the first n-side electrode and the second n-side electrode, a first p-side external connection electrode connected to the first p-side electrode, and a second p-side external connection electrode connected to the second p-side electrode.
