1. A light-emitting device comprising:

  • a substrate having a plane surface;

    a semiconductor light-emitting element mounted on the plane surface of the substrate and which emits light in a range from ultraviolet ray to visible light;

    a first light transmissible layer which covers the semiconductor light-emitting element and contacting with the plane surface of the substrate;

    a phosphor layer which covers the first light transmissible layer, the phosphor layer contacting with the plane surface of the substrate and containing phosphor particles and matrix, a surface of the phosphor layer having projections reflecting shapes of the phosphor particles; and

    a second light transmissible layer which covers the phosphor layer and contacting with the plane surface of the substrate.
