In a light-emitting apparatus using a silicone resin as a sealant of its light-emitting element, it is intended to prevent discoloration of its lead frame. A light-emitting element fixed to a lead frame is sealed with a sealed portion formed by a silicone resin. An average spin-spin relaxation time of the silicone resin is equal to or smaller than 100 microseconds at 25° C. at a resonance frequency of 25 MHz.
