ABSTRACT:
An illuminating device includes a light source including a light-emitting element, an electrode electrically connected to the light-emitting element, and a heat radiation terminal electrically isolated from the light-emitting element; and a multilayer substrate including a plurality of insulating layers, a plurality of metal layers, an electrically conducting interlayer contact portion, and a heat-conducting interlayer contact portion. The insulating layers include all insulating layer having a mount surface on which the light source is mounted with the electrode and the heat radiation terminal therebetween. The metal layers include an electrically conducting metal layer electrically connected to the electrode and disposed so as to be separated from the light source by the insulating layer having the mount surface and an electrically isolated metal layer electrically isolated from the other metal layers and disposed most distant from the mount surface of all the metal layers. The electrically conducting interlayer contact portion electrically connects the electrode to the electrically conducting metal layer. The heat-conducting interlayer contact portion connects the heat radiation terminal to the electrically isolated metal layer.
