Abstract
A chip-type light-emitting device with case ( ) includes an LED chip ( ) which is bonded onto electrodes ( ) formed on a substrate ( ). A case ( ) is arranged such that the LED chip is surrounded by a hole ( ). The hole has an inner wall ( ) tapering downward shaped like a frustum of a cone, in which transparent resin is filled as a sealant. When cured, the transparent resin hardens and shrinks, and therefore, a gap ( ) is formed between the inner wall and the transparent resin (sealant).
