Abstract

A heat radiation control element 11, which contains an inorganic layer 21 a surface of which has openings arranged two-dimensionally, and a reflecting film 22.

Claims

1. A heat radiation control element, comprising:

an inorganic layer a surface of which has openings arranged two-dimensionally; and

a reflecting film,

wherein the inorganic layer is either a quartz layer, or a glass layer.

2. The heat radiation control element according to claim 1, wherein an opening shape of each of the openings is a circle or a regular polygon.

3. The heat radiation control element according to claim 1, wherein the openings have opening diameters of 3 μ

m to 11 μ

m.

4. The heat radiation control element according to claim 1, wherein the openings have depths of 0.7 μ

m or greater.

5. The heat radiation control element according to claim 1, wherein the openings have an aspect ratio of 0.2 or greater.

6. The heat radiation control element according to claim 1, wherein the two-dimensional arrangement is a lattice arrangement, or a houndstooth arrangement.

7. The heat radiation control element according to claim 1, wherein the reflecting film is provided on an opposite side of the inorganic layer to the side thereof at which the openings are formed.

8. The heat radiation control element according to claim 7, further comprising a dielectric reflecting film between the inorganic layer and the reflecting film, wherein the dielectric reflecting film is a dielectric film of a single layer, or a laminate of dielectric films having mutually different refractive indexes.

9. The heat radiation control element according to claim 7, further comprising a protective film provided at an opposite side of the reflecting film to the side thereof at which the inorganic layer is provided.

10. The heat radiation control element according to claim 7, further comprising a transparent conducting film provided at the side of the inorganic layer where the openings are formed.

11. A production method of a heat radiation control element, comprising:

forming a resist pattern, in which predetermined shapes are two-dimensionally arranged, on a surface of an inorganic substrate, which is either a quartz substrate or a glass substrate;

etching the surface of the inorganic substrate using the resist pattern as a mask to form two-dimensionally arranged openings at the surface of the inorganic substrate; and

forming a reflecting film on a surface of the inorganic substrate that is opposite to the surface thereof where the openings are formed through vacuum deposition or sputtering.

12. A production method of a heat radiation control element, comprising:

laminating a dielectric film, a reflecting film, and a protective film in this order on one surface of an inorganic substrate that is either a quartz substrate or a glass substrate;

forming a transparent conductive film on another surface of the inorganic substrate;

forming a resist pattern, in which predetermined shapes are two-dimensionally arranged, on a surface of the transparent conductive film; and

etching the surface of the inorganic substrate using the resist pattern as a mask to form two-dimensionally arranged openings at the surface of the inorganic substrate.
