Surface-emitting light source and method of manufacturing the same

A surface-emitting light source comprising:

• a plurality of light-emitting modules;
• a wiring substrate including:
• a base member having a front surface at a light-emitting modules side and a rear surface opposite to the front surface at the light-emitting modules side,
• a wiring layer disposed on the rear surface of the base member and including wiring pads which are portions of the wiring layer,
• electrically-conductive members each supplied across corresponding two or more of a plurality of vias, the plurality of vias formed in each of the wiring pads, and
• a covering layer covering the wiring layer and defining pad openings in each of which a portion of a corresponding one of the wiring pads is exposed;
• and
• an adhesive layer between the plurality of light-emitting modules and the wiring substrate;
• wherein each of the light-emitting modules includes an array of a plurality of light emitting devices, and
• wherein the covering layer defines the pad openings at locations corresponding to the wiring pads with an area dimension smaller than respective area dimensions of the wiring pads in a plan view.
