Abstract
A light emitting device includes a package body, a light-transmissive cover, one or more semiconductor laser elements, a wavelength converting member, a wiring, electrically conductive layers, an opaque electrically insulating member, and electrodes. The light-transmissive cover is secured to the package body. The wavelength converting member is disposed above the light-transmissive cover in an optical path of the laser light emitted from the semiconductor laser element. The wiring is disposed on a light incidence surface-side of the wavelength converting member. The electrically conductive layers are electrically connected to the wiring and disposed on an upper surface of the light-transmissive cover. The electrically insulating member at least partially covers the electrically conductive layers and the light-transmissive cover. The electrodes are disposed on a surface of the package body at locations outward of the electrically insulating member in a plan view, and electrically connected to the electrically conductive layers.
