Light-emitting unit and surface-emission light source

A light-emitting unit comprising:

• a wiring board having a wire layer;
• a plurality of light-emitting elements provided in an array on the wiring board and electrically connected with the wire layer of the wiring board;
• a sheet-like light reflecting member provided on the wiring board, the light reflecting member having a plurality of throughholes;
• a plurality of wavelength conversion layers each covering an upper surface of a corresponding one of the plurality of light-emitting elements;
• a plurality of light reflecting layers each being provided on a corresponding one of the plurality of wavelength conversion layers and being capable of transmitting a part of incoming light and reflecting another part of the incoming light;
• and
• a protecting layer provided on at least a part of the light reflecting member, wherein
• each of the plurality of light-emitting elements is located inside a corresponding one of the plurality of throughholes in a top view, and
• the protecting layer has one or more grooves each located between two adjoining light-emitting elements in the array of the plurality of light-emitting elements, each groove penetrating through the protecting layer.
