Light-emitting device

A light-emitting device comprising:

• a substrate;
• a light-emitting element disposed on said substrate;
• a light transmitting member disposed on said light-emitting element;
• and
• a covering body that is disposed on said substrate, that covers a side surface of said light transmitting member, and that has an upper surface exposed to an outside of said light transmitting member,
• wherein:
• said covering body has a particle group composed of a plurality of particles dispersed in said covering body,
• said particle group includes a plurality of titanium oxide particles or zinc oxide particles dispersed in a vicinity of said upper surface of said covering body and each having a portion having a narrower band gap than in other portions of the particle, and
• said plurality of particles in said particle group are dispersed in a range of 5 to 70 wt % in said covering body.
