Abstract
A light emitting diode includes a light emitting body, a lead frame supplying power to the light emitting body and a light transmitting resin covering the light emitting body and part of the lead frame. The top surface of the light transmitting resin is formed as a plane at a position that satisfies a condition in which part of radiated light from the light emitting body is totally reflected. An inclined surface is formed at a position that satisfies a condition in which part of the radiated light is refracted in a downward direction away from a line perpendicular to the inclined surface.
