Abstract
A light-emitting diode with no fluctuations in optical properties and good sealing properties, and a simple production method for producing this light-emitting diode. The light-emitting diode has a base comprising a cup part on which the light-emitting diode is placed, a resin material introduced into cup part, and a lens member placed on top of a cup for focusing light emitted by a light-emitting diode chip. A layer of fluorescent material, which converts the wavelength of at least some of the light from the light-emitting diode chip, is applied to the inner convex face of the lens member. When the lens member is attached to the base, the inner convex face deforms the resin material and air and excess resin material can be pushed to the outside.
