Abstract
A nitride semiconductor light-emitting system includes a nitride semiconductor light-emitting device, a base mount holding the nitride semiconductor light-emitting device, having an opening, and containing first metal as a main component, a cap adhered to the base mount, and a lead pin penetrating the opening. The lead pin is fixed to an inner wall of the opening with an insulating member and a buffer member interposed therebetween, the buffer member and the insulating member being stacked on the inner wall in this order. The insulating member contains silicon oxide as a component. The buffer member is made of second metal having a smaller standard oxidation-reduction potential than the first metal, or an alloy containing the second metal.
