Patent abstract
A light-emitting device includes a laser diode element, a wavelength-converting member that absorbs light emitted from the laser diode element and converts wavelength of the light, and a transparent conductive film that is arranged on at least one of a light extracting-side surface and a laser diode element-side surface of the wavelength-converting member. The transparent conductive film is configured such that electrical resistance in a region overlapping the wavelength-converting member increases when the wavelength-converting member is damaged.
