A light emitting device includes a base having a first lead electrode and a second lead electrode. Each of the first lead electrode and the second lead electrode includes a reflecting layer which includes silver or silver alloy plating containing a sulfur-based gloss agent. A light emitting element is provided on one side of the base and is electrically connected to the first lead electrode and the second lead electrode. The reflecting layer is on the one side of the base. A sealer includes resin and is provided on the one side of the base to seal the light emitting element and at least a part of the first lead electrode and the second lead electrode. A light-transmissive protective film includes an inorganic matter and is provided between the reflecting layer and the sealer.
