Abstract
A light-emitting device includes a base member having an upper surface and a recess on an upper surface side; a light-emitting element disposed in the recess and configured to emit ultraviolet light; a light-transmissive member disposed on the upper surface; a first inorganic adhesive member disposed on the light-transmissive member; and a lens bonded to the light-transmissive member with the first inorganic adhesive member. An absolute value of a difference in linear expansion coefficient between the base member and the light-transmissive member is smaller than an absolute value of a difference in linear expansion coefficient between the base member and the lens.
