Abstract:
1. An illuminating device comprising: 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 an insulating layer having a mount surface on which the light source is mounted with the electrode and the heat radiation terminal therebetween, 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 electrically conducting metal layer and disposed further from the mount surface than the electrically conducting metal layer, an electrically conducting interlayer contact portion electrically connecting the electrode to the electrically conducting metal layer, and a heat-conducting interlayer contact portion connecting the heat radiation terminal to the electrically isolated metal layer.
