Abstract
A light emitting device includes: a base including: a first lead including: a first A surface, a first B surface opposite to the first A surface, and a first C surface located between the first A surface and the first B surface and defining at least one first protrusion, a second lead separated from the first lead, and a resin body covering the first C surface and holding the first lead and the second lead; a light emitting element disposed on the first A surface; and a protecting member disposed continuously on at least a portion of the first A surface and in at least a portion of a gap between the first protrusion and the resin body. In a cross-sectional view, the first protrusion extends from a first end portion of the first A surface at a second lead side toward the second lead.
