PROBLEM TO BE SOLVED: To provide a substrate having a desired pattern on a surface and achieving reduction in the number of process and low cost accompanied by the reduction in the number of process, a method for manufacturing the same, and a light-emitting element and a method for manufacturing the same.SOLUTION: Photosensitivity is granted to a dielectric film composition itself and concave section pattern can be formed even with no photoresist film. A flat substrate 1a is prepared, a dielectric substance having photosensitive agent is formed on the substrate, the dielectric substance is subjected to pattern forming, and the dielectric substance having a desired pattern is formed on a surface of the substrate. A substrate 1 is obtained that has a pattern made of an island-like concave section 1b on a surface of the flat substrate and whose concave section is composed of the dielectric substance.SELECTED DRAWING: Figure 2 【課題】工程数の削減と、工程数削減に伴う低コスト化を可能とした、所望のパターンを面上に有する基板とその製造方法、及び発光素子とその製造方法を提供する。【解決手段】誘電体膜組成そのものに感光性を付与し、フォトレジスト膜無しでも凸部パターン形成を可能とする。平坦な基板１ａを用意し、感光剤を含有する誘電体を基板面上に形成し、誘電体をパターン形成して、所望のパターンの誘電体を基板面上に形成する。平坦な基板の面上に、島状の凸部１ｂからなるパターンを有し、凸部が誘電体から構成される基板１を得る。【選択図】図２
