Abstract
A light-emitting diode capable of making its light emission more uniform without too high a concentration current and of improving the efficiency of outgoing light and its life. In the light-emitting diode, the n-side electrode has an n-side connecting portion and an n-side extending portion, which extends in the longitudinal direction from a predetermined part of the n-side connecting portion, and the p-side pad member has at least a p-side connecting portion to be connected to a conductive member. The light-emitting diode further includes an n-side connecting area, in which the n-side connecting portion is provided, provided in proximity to one end in the longitudinal direction, a p-side connecting area, in which the p-side connecting portion is provided, provided in proximity to another end in the longitudinal direction, and a middle area provided between them, and the n-side extending portion is positioned in the middle area, and extends so as to be opposed to the p-side current diffusing member.
