All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method of manufacturing a light-emitting device, the method comprising:
placing a phosphor-containing film on a mold for compression molding, the mold comprising a concave portion of a predetermined shape and the film being placed along an inner wall of the concave portion;
supplying a resin material on the phosphor-containing film in the concave portion;
immersing a light-emitting element mounted on a substrate in the resin material in the concave portion; and
applying pressure and heat to the resin material and the phosphor-containing film, thereby forming a transparent sealing resin for sealing the light-emitting element and a phosphor-containing layer covering a surface thereof,
wherein the phosphor-containing film is placed so as to be in direct contact with the inner wall of the concave portion, and
wherein the phosphor-containing layer functions as a release film when the substrate, the light-emitting element, the transparent sealing resin, and the phosphor-containing layer are released from the mold.
2. The method according to claim 1, wherein the phosphor-containing film comprises a concavo-convex surface on one side thereof.
3. The method according to claim 1, wherein the phosphor-containing film comprises a concavo-convex surface on both sides thereof.
4. The method according to claim 1, wherein the phosphor-containing layer is thicker at a portion on an apex of the transparent sealing resin than at a portion on a side portion of the transparent sealing resin.
5. The method according to claim 1, wherein the transparent sealing resin has a hemispherical shape.
6. The method according to claim 1, wherein said supplying the resin material on the phosphor-containing film comprises filling a cavity in the concave portion with the resin material.
7. The method according to claim 6, wherein, in said filling the cavity in the concave portion with the resin material, an upper surface of the resin material is flush with an upper surface of the phosphor-containing film.
8. The method according to claim 1, wherein said supplying the resin material on the phosphor-containing film in the concave portion is conducted before said immersing the light-emitting element in the concave portion.
9. The method according to claim 1, wherein the resin material is placed in the concave portion separately from placing the light-emitting element in the concave portion.
10. The method according to claim 1, wherein the phosphor-containing film comprises a plurality of concavo-convex surfaces on one side of the phosphor-containing film.
